How to Juice Star Fruit Using a Blender

Living on a farm in Brazil, I've gained local in-depth knowledge of food, plants, and traditions, which I share through my articles.

How to Juice Star Fruit

How to Juice Star Fruit

Star Fruit is Also Known as Carambola

My friend here in Brazil has a star fruit tree and always has a surplus of fruits that she sends home with visitors. I recently came home with a large bag and decided to juice some of them to have with dinner.
Although many people know it as star fruit because of its shape, it is called carambola.
If you are buying your star fruit in a supermarket, the fruits may all be a uniform size. When you get them from a friend, straight from the tree, the sizes will vary. The reason I'm telling you this is there will still be guesswork involved in making your juice, but don't worry, it's going to turn out great, I promise.
The ingredients needed to make the juice are simple, just star fruit, sugar (or your choice of sweetener), and water. That's it! No artificial coloring or E numbers.
It's unlikely all your fruit will all be at the same point of ripeness, mine wasn't either, and that's okay. If your fruit isn't prepacked in the supermarket, carefully examine them for soft spots before purchasing. The skins are fragile and, once damaged, begin to rot quickly. The ridges should be firm and not floppy. If they are slightly green, that's okay. Avoid buying any which are turning brown as they may be overripe. If you purchase the ones with a greenish tinge, they will ripen up well at home in a fruit bowl.


  1. Start by washing your fruit. Place them in a colander and rinse with running water. Cut out any soft spots and discard. If there are any bits of stem attached remove this as well.
  2. Now cut into pieces. As you can see from my images, my chunks are quite large, the fruits are juicy so this isn't a problem. There is no need to remove the seeds, we will be doing this at the end. I fill my blender almost to the top. You don't want it to splash out so leave a little space. I used 7 fruits of varying sizes. Reserve a few slices for decoration if you want to add a bit of pizzazz to your presentation.
  3. I use about 1/3 cup of white sugar which makes a juice which is tangy enough but not too sweet. You will have to judge this for yourself. The quantity of sugar you use may be different.
  4. Add the water, I use a liter of cold water, which is about a quart.
  5. Then switch the blender on. Because the fruit is quite firm, I need to use a medium setting to get it going, otherwise I can hear the motor straining. You know the capabilities of your blender, and can judge accordingly. If your blender is struggling, turn it up to begin with. This won't take but a few seconds to break the fruit down. When you don't see any large bits flying by in the jug, you can switch off the machine.
  6. The next step is slightly fiddly but will enhance your juice drinking experience so it is necessary. Simply place a funnel inside the serving pitcher and place a sieve over the funnel. I use a fine mesh sieve, the finer the sieve, the smoother the juice. This may take some time but pour some of the juice into the sieve leave enough space at the top so it doesn't slop over. With a spoon or rubber spatula gently scrape back and forth. The juice will fall below and the pulp, seeds and skin with remain in the sieve. When your sieve has too much pulp in it, press out as much juice as you can with the back of a spoon, then transfer the pulp to a bowl. Continue as before until all the juice from the blender jug has been used up.

Foam on Top of Juice

You will notice that your juice has separated and there is a froth at the top. If you place a long spoon in the jug, everyone will know to stir it before pouring into their glass. If you prefer to pour it straight into glasses, giving the person either a straw, swizzle stick or spoon will help them reincorporate the foam into the juice at the bottom. If they drink it with the foam, they will end up with a foamy mustache.

Decorate with Star Fruit

The slices of star fruit you reserved can be used in a couple of different ways.

  1. If serving your juice from a jug, these can be placed in the juice.
  2. If serving in a glass, cut a small incision and place on the rim, as shown in the picture.

In my experience, I don't serve juice with ice. The reason being I don't like overly diluted juice and if the ice begins to melt, that's what you'll have.

Why you Should Always Use a Straw for Juices

If you've always drunk your juice or soft drinks from a glass or can without a straw stop it now. I'm serious, you are damaging your teeth by not using a straw.

The acid which is found in fruit juices and also in soft drinks will eat away at the enamel on your teeth. My daughter is a dental therapist in London and always advises her clients to avoid soft drinks or at least use a straw. The same holds true for juices, especially those high in vitamin C or ascorbic acid.

That is a good tip about using a straw to avoid the acid eating away at one's teeth when drinking juices or sodas. I have only eaten star fruit slices, but never had just the juice. It is great that you have a friend with a star fruit tree.

Mary Wickison (author) from USA on December 19, 2017:

Thanks Mary, I will see if I can find some premade dough. Although I always make my own pie crusts, I think spring rolls are more of a puff or filo pastry, aren't they?

Hi Thelma,

I'm with you, I will happily eat them but my husband prefers them juiced. They have a wonderful tropical taste.

Merry Christmas to you as well.

Mary Norton from Ontario, Canada on December 16, 2017:

I asked my Vietnamese friend in Hanoi once to show me how to do fresh spring rolls and she used star fruit. I was also surprised but she told anything abut sour is good like star fruit and apple. It was refreshing. Just julian cut it.

Mary Wickison (author) from USA on December 16, 2017:

Hi Mary,

You have me intrigued by the spring rolls. I don't think I have had any with apple or star fruit. I think only the type of cabbage and carrots. I'd love a recipe.

Thanks for your comment.

Thelma Alberts from Germany on December 15, 2017:

Thanks for this recipe Mary. I have a star fruit tree in my Philippines garden and I have not tried making juice out of the fruits. Just eat them as fruit salad and as they are.

Merry Christmas and a Happy New Year.

Mary Norton from Ontario, Canada on December 14, 2017:

Hi Mary,

We have this plant in our garden in the Philippines. My friends in Vietnam use it for fresh spring roll instead of the apple. I have never juiced it but will now send this link to my sisters.

By the way, I appreciate your comment very much in my article on Afurada but I can't respond to it. Anyway, it is very close to Porto.

Mary Wickison (author) from USA on December 09, 2017:

Hi Jackie,

I hope you'll soon be enjoying a glassful of this wonderful juice. Thanks for reading.

Jackie Lynnley from the beautiful south on December 08, 2017:

Thanks Mary, this is great to know for I did not and I do like this fruit.

Mary Wickison (author) from USA on November 30, 2017:

Hi Chitrangada,

I too love eating it either in a fruit salad or on its own. My husband finds it too tart and prefers it in a juice. Along with passion fruit, the star fruit is fast becoming one of our favorites.

Thanks for your comment, I'm pleased your enjoyed the article.

Chitrangada Sharan from New Delhi, India on November 29, 2017:

Nice, informative article about star fruit! I have eaten it many times, but never in juice form. It’s much easier to consume it this way and thanks for sharing the process of preparing the juice.

Thanks again for the reminder of using straw for juices. Valid reason for doing so.

Well written and informative article. Thank You for sharing!

Mary Wickison (author) from USA on November 24, 2017:

Hi Nell,

I'm sure they have it in the UK. My juicer is temperamental at the moment so am using my blender.

If you get the chance to make it, I think you'll enjoy it.

Thanks for reading.

Nell Rose from England on November 24, 2017:

great advice Mary! my juicer sadly broke a few months back, but its definitely on my list.

I don't think I have ever tried star fruit, I will have to look out for it.

Mary Wickison (author) from USA on November 16, 2017:

Hi Daniel,

I'm glad you found the article interesting.

When my daughter came to visit me here in Brazil, I asked her to bring her dental tools so she could give me a check-up.

That is when she told me my enamel was getting thin and explained to me about the relationship of acids in soft drinks, juices, and even coffee.

If you drink these during meals, your teeth are only under attack during that time and about 30 minutes after.

There are some people who consume soft drinks all day long.

I hope your situation with your teeth subsides.

Take care and thanks for your comment.

Jay Daniel on November 16, 2017:

I like the detailed presentation of this tutorial on how to make juice from a star fruit and I can't wait to try it out.

What impresses me the most is the aspect of the disadvantage of drinking a juice or soft drink without a straw, honestly speaking, I never knew about this. I have been drinking juices and soft drinks without straws almost all my life until today. But reading this article just now have made me realize. And I think this also explains the reason why I have some unusual feelings in my teeth after drinking juice or soft drinks sometimes.

Thank you Mrs. Mary Wickison for this eye opener.

Mary Wickison (author) from USA on November 13, 2017:

It the same here, those that you listed excluding the sour sop, are always in the stores. I have only seen the sour sop for sale once or twice. It is good to know people with the trees in their gardens.

I too hope they keep the traditional fruits.

Maria Cecilia from Philippines on November 13, 2017:

Probably because we have more popular fruits like mangoes, banana, guava, sour sop, papaya and others, and children then were not really fond of the fruit. But i wish there are groups that started to revive our old fruits, Balimbing and star fruit is just one of them. We have chesa, alatiris, duhat lot more..

Mary Wickison (author) from USA on November 13, 2017:

Hi Maria,

I am surprised to hear that they aren't grown as widely as before. I don't know much about the culture of the Philippines other than what I've read from people online.

Good food always seems to be mentioned though. It is somewhere I hope to visit one day and sample the food for myself. Everything except for balut, I'm not sure I'm ready for that.

Maria Cecilia from Philippines on November 13, 2017:

This looks like a fruit that I always see when I was a kid. A we called that fruit balimbing, I googled and I realized our balimbing is what you called the star fruit. Balimbing in filipino means many faces, probably referring to the edges or equal edges... Star fruit is considered an old Philippine fruit and I rarely see them these days. But I guess because of the health benefits, Filipinos will start planting them again. Thanks so much for your wonderful hub...what an enlightenment...

Mary Wickison (author) from USA on November 13, 2017:

Hi Linda,

When Bill commented that he wouldn't be able to find the star fruit in the stores, I had a look at where it grows. I was surprised to see that even in Northern California it would grow. The growing zones are 9-11 outside. However, on a patio 4-11.

Until grocery stores see there is a market for it, they won't risk buying it.

I see this here, there are so many fruits I'd never seen before coming to Brazil but no one grows them commercially. It will only be in someone's back garden or growing wild.

I hope you're able to find it locally as it makes a lovely juice.

Thanks for reading.

Mary Wickison (author) from USA on November 13, 2017:

Hi FlourishAnyway,

Although I don't normally add sugar to our juices there are some, we just have to. Normally for star fruit, passion fruit, and lemon I always do.

However, I have found the way to get around adding sugar is to combine two different fruits. We are coming into our mango season soon and mango juice will be on our dinner table for about 4 months. I will often use any of the citrus fruits to help give the mango juice a bit of zing. We also have a couple of Barbados cherry trees which are high in vitamin C, these not only give mango juice a nice flavor it increases the vitamin content.

Thanks for reading, have a wonderful week.

Linda Crampton from British Columbia, Canada on November 12, 2017:

You've encouraged me to try star fruit and its juice myself. Thanks for the idea! I'll buy some of the fruit when I find it.

FlourishAnyway from USA on November 12, 2017:

I’ve tried star fruit before and they really made me pucker but not as much as a lemon. I’d love to add sugar and try this drink for a change of pace.

Mary Wickison (author) from USA on November 12, 2017:

Hi Dora,

It's funny you mention that because when I was returning from my friend's house with my bag of the star fruit, I ate one while driving. I must have picked the greenest one in the bag because it was so tart. Trying to drive with my lips puckered and my eyes squinting, thank goodness we never have traffic in my area.

I enjoy eating them as well but normally in a fruit salad with other sweeter fruits. I like to put honey on top just to take the edge off of them.

I love the availability of fresh fruit here and I am certain our climates must be similar and share many of the same bounties of nature.

To tell you the truth, I juice them because that is the only way I could get my husband to consume them. I can't recall the last time he ate a piece of fruit. This is the complete opposite to me as I eat fruit daily.

Thanks for your comment.

Dora Weithers from The Caribbean on November 12, 2017:

Star fruit is common in my neighborhood, and I like to eat as well as juice them. Thanks for your instructions and for the reason to use straws.

Mary Wickison (author) from USA on November 12, 2017:

Hi Kari,

Thanks, I know many people think that straws are for kids but if we plan to keep our teeth in our mouth and not in a jar by the side of the bed, we need to take care of them. Using a straw can only help.

Thanks for reading and your comment.

Kari Poulsen from Ohio on November 12, 2017:

This is very informative. I love that you brought up using a straw for juices and soft drinks. I have never really thought about this before, but it makes so much sense. :)

Mary Wickison (author) from USA on November 12, 2017:


I'm sure you can get them up there. I've just read they even grow in Sacramento.

Not only do they make a wonderful juice, they look great in a fruit salad.

I hope your Sunday is going well.

Mary Wickison (author) from USA on November 12, 2017:

Hi Simon,

Yes is the answer to that, just don't brush your teeth for about 30 minutes. That is the reason it is suggested to drink juices or soft drinks with the meal and not by themselves. For about 30 minutes your teeth are being attacked with acid. A quick rinse with water helps.

If you were to brush you could be stripping your protective coating of enamel off.

The juice is really good and is one of our favorites along with passion fruit juice.

Thanks for reading and your comment.

Bill Holland from Olympia, WA on November 12, 2017:

Difference in cultures: I had no idea what the title of this article meant. LOL Thanks for the education. Probably no chance I'll ever see a star fruit in Olympia but one can always hope. :) Happy Sunday, Mary!

Simon Lam on November 12, 2017:

Great article Mary! Clear instructions and photos! I'm sure it tastes really good.

I wonder if rinsing your mouth with water after drinking acidic juices helps prevent the acid attack on your teeth?
