Jackfruit Explained + Jackfruit Curry (Polos) Recipe

Many years ago, when I just moved to Sri Lanka, I decided that jackfruit was going to be my favorite fruit. I say “decided” because I distinctly remember the moment when I made that decision. I was at a farmer’s market in Colombo, having my lunch of rice and curry prepared by a local lady. I pointed at one of the curries that looked unfamiliar and asked what it was. “Jackfruit seeds curry,” she replied. “As in… just seeds? No jackfruit flesh whatsoever? You mean like… a curry that consist entirely of seeds?” I asked her the same question in about five different ways and each time she replied with “yes”. 

My mind was blown. By that time I already knew that jackfruit can be a lot of different things to different people: a fruit, a vegetable, a rice substitute, a meat substitute. And now you are telling me even its seeds can be cooked on their own? 

Imagine you meet a person who says that he has a PhD in applied mathematics, but he works as a brain surgeon, and he also speaks five languages, and on top of all that he is a published poet. That’s how I feel about jackfruit. How can one food be so many things at once?

Heatlh Benefits of Jackfruit

Apart from being so versatile, jackfruit has a whole bunch of health benefits. It is rich in potassium, calcium, and iron that make it nutritious. 

Jackfruit also has high level of dietary fiber and lower calorie count than rice and bread which means it’ll satisfy hunger faster, and you will feel full longer, all the while consuming less calories than if you were eating rice or bread. Dietary fiber also aids digestion and therefore improves metabolism. 

Jackfruit seeds contain a good amount of protein which makes them perfect for vegan and vegetarian diets. 

According to the numerous articles on the web, jackfruit can pretty much singlehandedly cure at least a dozen diseases: from improving vision to fighting cancer to curing insomnia. Just google “jackfruit benefits” and prepare to be amazed. Seriously, though, eating jackfruit can help maintain blood pressure due to its high potassium level, strengthen bones due to its calcium content, and help reduce the risk of heart disease thanks to vitamin B6.

Is Jackfruit the New Superfood?

Superfood is a funny phenomenon. Here you are, born and raised in Sri Lanka, cooking with coconut oil and adding coconut milk to curries your whole life just because it’s been done this way for hundreds of years. Also, because coconuts are available and cheap, but surely not because they are trendy. Next thing you know coconut oil is this magic ingredient everyone is craving, and people are ready to pay big bucks for it. First it happened to coconut oil, then to coconut milk, then to turmeric, all of which are very common in Sri Lanka. Jackfruit seems to be the next big thing. But I can understand why. 

For one thing, jackfruit is huge. It is the biggest tree borne fruit. Even a small jackfruit weighs 10-15 lb (5-7 kg) on average, and can go up to 50-60 lb. There are even recorded specimens of 100 lb and more. What it means is that one jackfruit can feed a lot of people. 

According to the article in the Guardian:

“The World Bank and United Nations warned recently that rising temperatures and unpredictable rainfall had already reduced yields of wheat and corn, and could lead to food wars within the decade. Now researchers say jackfruit could help provide the solution.”

In the same article, Danielle Nierenberg, president of Food Tank, which works on sustainable agriculture, is quoted:

“It is easy to grow. It survives pests and diseases and high temperatures. It is drought-resistant. It achieves what farmers need in food production when facing a lot of challenges under climate change.”

In Sri Lanka, with its abundance of jackfruit, it is considered to be a poor man’s food. Those who can’t afford to buy rice, eat jackfruit instead. But is it really a bad thing? The ability of one fruit to be not only incredibly versatile, but also to feed a whole family. To my mind, it’s only one more reason to love it.

Jackfruit in Sri Lanka

You know how Eskimo have about fifty different words to describe snow? It’s kinda like that with jackfruit in Sri Lanka. On different stages of its life, jackfruit has different names. Here are the main three: polos (young jackfruit, baby jackfruit), kos (ripe jackfruit), waraka (overripe jackfruit). The reason you need to know this is because on different stages the taste of jackfruit varies. It’s not like eating underripe banana and ripe banana. It’s more like eating a banana and an apple. The tastes are so completely unalike, that if you tried polos curry and kos curry for the first time, you would never think they are made from the same fruit. Another thing to note, at different stages jackfruit is cooked differently (or not cooked at all).

Polos, Young Jackfruit

At its first stage, jackfruit is called “polos” in Sri Lanka. You can also hear the names “young jackfruit” or “baby-jackfruit”. At this stage, the bulbs with seeds are not yet formed and the whole fruit is cut into pieces for cooking.

In Western countries, polos is referred to as “green jackfruit”. Canned green jackfruit is easy to find in the isles of Asian food in supermarkets, in Indian grocery stores, or online. Which is why polos curry is the easiest to make when you live outside of South East Asia (check out my mother-in-law’s recipe for polos curry below).

Polos (young jackfruit) curry reminds pulled pork in consistency.

Polos curry is the most popular way of preparing young jackfruit in Sri Lanka. Once cooked, the pieces resemble pulled pork in texture. The curry is full of spices and is usually on the hot side. 

Because of its meat-like consistency, many vegetarian recipes include polos as a substitute for pork, for example, in a pulled jackfruit burger or a sandwich. But although the texture is similar, polos doesn’t have the same amount of protein as meat, so you should substitute it wisely.

Kos, Mature Jackfruit

At its second stage, jackfruit is called kos. This is when jackfruit is mature and fully grown in size. The bulbs with seeds inside are fully developed. The fruits are so big they are usually cut and sold in pieces.

At the second stage (kos), bulbs are fully formed and used for cooking.

Kos bulbs are cut into pieces to be boiled or cooked as a curry.

Kos in Sri Lanka is used to make a curry called kiri kos maluwa. Kiri kos is very different from polos curry both in texture and taste. It is very creamy, tangy, and starchy. Chili is usually not added to the mixture, so the curry has a very mild and milky taste.

Unlike polos, kos is pretty much impossible to find outside of South East Asia. Your best bet is to travel to Sri Lanka and try it here (totally worth it, I think!)

Waraka, Ripe Jackfruit

The last stage of jackfruit is when it becomes ripe. At this point you don’t need to cook it. Just cut waraka up, extract the yellow bulbs, remove the seeds, and stuff your face with sweet fleshy petals.

Canned waraka, just like canned green jackfruit, can be found abroad. If you see tins with the name “jackfruit in syrup” in supermarkets, that’s waraka.

Jackfruit Seeds

Not only the flesh of jackfruit is edible, but its seeds are too. Polos doesn’t have fully formed seeds as it is too young, but kos and waraka have large seeds that can be extracted and boiled in pressure cooker. Afterwards, they are cooked into a curry called kos atta maluwa.

Sri Lankan Jackfruit Curry (Polos) Recipe

Of all possible ways to cook jackfruit, I want to start with Sri Lankan polos curry. Why? Because it’s delicious, you can find ingredients pretty much anywhere in the world (canned green jackfruit is fairly common), and that’s what was for lunch at home today.

In Sri Lanka, polos curry is served with rice and several other curry varieties. You can do that or you can just make the curry and use it however you like: stuff a sandwich with it, serve over grains, or eat it on its own (spicy!).

Below is my mother-in-law’s recipe for polos curry. It explains how to make traditional Sri Lankan polos curry with fresh young jackfruit and fresh coconut milk. If you don’t have access to fresh ingredients, substitute them for canned jackfruit and canned coconut milk. I am going to try out the recipe with canned ingredients as soon as I get my hands on them. Turns out it’s really hard to find canned jackfruit in Sri Lanka where fresh one is in abundance.

White sap inside young jackfruit is very sticky. Use coconut oil to prevent it from staying on the knife and your hands.

Tips for working with fresh polos and fresh coconut milk:

  1. When cutting fresh jackfruit, be prepared that it’s a messy affair. There’s white sticky sap inside that will stick to your hands, the knife, and the cutting board. Wipe it off with any kind of cooking oil.
  2. Cutting through the spiky exterior is a little difficult and requires some strength on your part.
  3. Leave peeled and cut up pieces of jackfruit in water to avoid discoloring.
  4. I have described the process of breaking a coconut in half and extracting coconut milk in this post. In Sri Lanka, extracted milk is separated into three categories: first, second, and third; first milk being the creamiest and third milk being the least fatty, almost transparent one. You’ll need first and second coconut milk for this recipe.
