How to Make Tamarind Paste from Pulp

Why You Should Never Buy Tamarind Paste Again

If you've been buying ready-made tamarind paste or tamarind concentrate for cooking, like I used to, let me tell you why I stopped and what I do now. Growing up in Thailand we always made our own tamarind paste for cooking, but when I arrived in Canada I was delighted by the convenient jars from the store!

But after years of using it, I don't know if the products became worse or my standards became higher, but I eventually I became more and more dissatisfied with the quality of premade pastes.

They sometimes started to taste really bland and diluted to me. And while this isn't the case with all brands, all the time, it was inconsistent enough, even within the same brand, to warrant another solution.

Tamarind pulp (in block form) can be turned into homemade jars of delicious tamarind paste, used in many Thai recipes.

Why Making it Is the Way to Go

So I started making it from tamarind pulp, the traditional way, and found the result to be more flavourful, more sour, and also more consistent. Tamarind pulp is that dark brown brick labelled simply as "Tamarind." You can find it at many Asian grocery stores, and it also usually says "seedless" on the package.

The good news is that it also keeps very well. But to make it last, you have to cook it, and then store it in a well-sealing jar such as mason jars. I now make tamarind using half a pound of pulp per batch, and I only have to make it about twice a year.

Tamarind pulp commonly sold at Asian markets. It is seedless, but still contains a lot of fibers that need to be strained out.

How long does homemade tamarind paste last?

If you cook the paste and store it in a mason jar as per my instructions, it will last up to 6 months, unopened in the fridge. Once it's opened, it has lasted me at least 2 months, but you have to be sure to always use clean utensils to scoop from the jar, and always put it back promptly in the fridge.

Because of this, I recommend you putting it in small jars, no larger than 1 cup per jar, to maximize its shelf life.

You can also can the tamarind, like you would jam and other canned products, and it will be shelf-stable. Though I have not personally done this.

What is tamarind?

Simply put, tamarind is a fruit. Its sticky brown flesh ranges from being very sweet to very sour, depending on the variety. The sweet ones are for eating fresh, and the sour ones are for turning into a paste for cooking.

Homemade Tamarind Paste

Homemade tamarind paste is much better than anything you can buy, and it is easy to make. For the best pad thai, you gotta use homemade tamarind! Be sure to watch the video tutorial below as the process can be much better understood once you see it, and you can also watch it on YouTube.

Cook Time 20 minutes
Cooling time 20 minutes
Servings 2 cups

Ingredients

  • ½ lb seedless tamarind pulp (see note)
  • 2 cups hot water

Instructions

  • Use your hands to pull apart the tamarind block into small chunks and place it in a large, heat-proof mixing bowl. Pour the hot water over the tamarind and let it sit until it’s cool enough for you to handle, about 20 minutes, though you can let it sit for as long as you need at this point—the longer it sits, the easier the next step will be.

  • Use your hand, preferably gloved if you don’t want tamarind stuck in your nails, to squeeze and scrunch the pulp to loosen it from the fibers. You should end up with something that has a consistency of a smoothie.
  • Once you can feel that most of the pulp has been released from the fibers, strain the tamarind mixture, into a pot through a sieve or a colander, preferably not fine-mesh, as the paste will be thick. Push as much of the liquid through as possible, and scrape the bottom of the sieve occasionally.
  • Gradually pour about ½ cup of room temperature water over the remaining fibers in the sieve while using your hand to mix it around. This will rinse off any last little bit of tamarind still stuck in the fibers.
  • You can use this right away for cooking, but for storage, cook the tamarind paste over medium high-heat until it boils, stirring constantly, as it is quite thick and can bubble and jump at you if you don’t stir. Allow it to bubble for 4-5 minutes to ensure that it is thoroughly heated through before turning off the heat.
  • Transfer the hot tamarind paste to clean, small mason jars, no larger than 1 cup capacity. I like using the smaller ones so each jar will not be open for as long. Close the lids while still hot and and allow it to cool at room temperature before moving them to the fridge for storage. As it cools the lids will be sucked in and it will seal very well, like jam, but since this was not properly canned, you still need to store them in the fridge.
    You can also freeze them in ice cube trays and store the cubes in freezer bags.

Notes

Note: Buy tamarind pulp that comes in a rectangular block, and it should be a product of Thailand. Do not use tamarind pulp from whole pods, as those are sweet tamarind meant for eating, not for cooking.

Tom yum goong maybe the most famous soup of Thailand, but its milder creamier sister, tom kha gai , is my personal favourite. This comforting Thai coconut chicken soup recipe is infused with the classic Thai herbs: lemongrass, galangal, and makrut (kaffir) lime leaves. It's so easy yet so loveable that when someone asks, "I'm new to Thai food, what should I try/make first?" Tom kha gai is my answer.

If you love mangoes, and you love mango desserts, Mango Royale, aka Mango Float, is an absolute must-try; right after mango and sticky rice , of course! It's a frozen Filipino dessert that takes advantage of peak-of-the-season mangoes, and uses only 5 ingredients. There's no baking involved, and it's so easy it's essentially fool-proof!

I LOVE all kinds of basil, but I don't love how quickly it goes bad and that it doesn't freeze well. So I came up with this recipe as a way to use up any amount of basil you have on hand . It's an easy and versatile sauce that only uses pantry staples, and can be stored in the fridge for at least a week. Reheat it and pour onto any cooked protein, or use it as a stir fry sauce - or heck, you can even use it as gravy for your mashed potatoes. It can also be made vegan. The possibilities are endless!

Imagine this: soft and creamy ice cream bars that you didn't need to whip or churn. All you have to do is cook the ice cream base, pour it into a mold, then cut it into pieces. And it's so soft your teeth will glide right through it as you take a bite, and it's wonderfully chewy. Yes, chewy.

I wanted a fried rice recipe that really celebrates the flavours of chilies - not just their heat. This fried rice features not one, not two, but three different types of chilies, combined with the fragrance of Thai basil to tie it all together! And no, it doesn't make this dish overwhelmingly spicy, and you can indeed customize the heat level while still preserving all the delicious chili flavour. It's not something I created out of thin air, but a traditional Thai dish (with a couple of tweaks from me)!

If you love cooking Asian food, oyster sauce is probably already in your kitchen. But do you know if the one you have is a "good one”? And is the expensive oyster sauce you bought (or didn't buy) worth the splurge?

Pad see ew is one of the most well-known and well-loved Thai dishes, but most people only know of the more common version of pad see ew that uses fresh wide rice noodles (ho fun). This version however uses thin rice vermicelli, and it's the one that I actually grew up eating in Thailand. It’s an incredibly fast dish to make; from the time I get up to cook to the time I sit down to eat, it takes only 20 minutes! You can even watch me prep and cook it all up in real time in the video tutorial below just to see how fast it really is!

Easy, delicious, and versatile; what else could you ask for in a chicken recipe? Lemongrass chicken is a staple menu item in Vietnamese restaurants in Canada, and one that my husband gets all the time - which is why I was inspired to recreate it. It is so quick to prepare, kid-friendly, can last you the whole week in the fridge (yay meal prep), and you can grill or broil it!
