Imli (Tamarind) Pulp From a Block: Soak, Strain, Store and Use
Most people buy a 250 g block of imli, hack off a lump, drown it in boiling water and end up with thin brown liquid and a fistful of wasted fibre. Getting proper imli pulp out of a tamarind block takes warm water, patience and two extractions, and this guide gives you the exact method, how long it keeps, and when all that sourness needs a little care.
Before you start
- Ratio: 50 g seedless block to 150 ml hot water, then a second 50 ml wash
- Soak time: 15 to 20 minutes
- Yield: roughly 150 to 180 ml of thick pulp
- Keeps: about 2 weeks in the fridge, 3 months frozen in cubes
- Watch out for: tooth enamel, acid reflux, and very large servings

Buying imli: block, whole pods or jar?
You’ll see three forms in a desi grocery. Whole pods, brittle and cinnamon-brown, are the freshest but slow to clean. Pressed blocks are the everyday choice. Jarred concentrate is convenient and usually darker, saltier and sharper, sometimes with added acid or preservative, so read the label.
A good block feels slightly soft and tacky when you press it, like a firm date. It should smell fruity and sour, a bit like raisins soaked in vinegar. Pass on blocks that are rock hard all the way through, dusty grey on the surface, or smell fermented and boozy. Small white crystals can be sugar blooming out of the fruit, which is harmless. Fuzzy spots, green or black, are mould. Throw the whole block away.
“Seedless” blocks still hide the odd seed and a lot of stringy fibre. That’s normal. Old stock goes almost black and very dry, and it gives a bitter, flat pulp no matter how long you soak it.
How to make imli pulp from a tamarind block
This is the method that gets the most out of every gram. Warm, not boiling, water softens the flesh without cooking a bitter edge into it.
- Break 50 g of block into 5 or 6 small pieces with your fingers. Smaller pieces soften faster.
- Put them in a steel or glass bowl and pour over 150 ml of hot water, about 80 °C (just off the boil, after a minute’s rest).
- Leave for 15 to 20 minutes. Press a piece with a spoon; it should collapse like wet clay.
- Squeeze and rub the pieces between your fingers for a full 2 minutes, working the flesh off the fibres. The water turns thick and chocolate brown.
- Pour through a medium steel strainer set over a clean bowl. Push the pulp through with the back of a spoon and scrape the underside of the strainer, where the thickest part clings.
- Return the leftover fibre to the soaking bowl with another 50 ml of hot water. Squeeze again for a minute and strain into the same bowl.
- Discard the fibres and seeds. You should have a pourable pulp about as thick as ketchup.
In a hurry? Put the pieces and water in a small pan and simmer on the lowest flame for 5 minutes, then cool until you can handle it. You lose a little brightness but save a quarter of an hour.
The ice-tray habit
Make a 150 g batch (three times the recipe above, with 450 ml then 150 ml water), cool it and pour it into an ice-cube tray. A standard cube holds about 1 tablespoon. Pop the frozen cubes into a zip bag, and a sambar or chutney is never more than a cube away.
Storing pulp and blocks
| Form | Where | Roughly keeps |
|---|---|---|
| Unopened block | Cool cupboard | Several months |
| Opened block | Wrapped, airtight jar | 3 to 6 months |
| Fresh pulp | Fridge, glass jar | About 2 weeks |
| Pulp cubes | Freezer | About 3 months |
Always use a dry spoon. Imli is acidic, so store pulp in glass or steel rather than aluminium or cheap plastic, which can pick up a metallic taste. If the fridge pulp grows a skin of mould or smells like alcohol, bin it.
Cooking with imli, and how much to use
Tamarind is sourness with body. Lemon is sharp and quick; imli is round, a little sweet, and it lingers. That’s why it sits at the heart of so many dishes.
Everyday amounts
- Sambar or rasam for 4: 2 to 3 tablespoons pulp, added once the dal is in, then simmered at least 5 minutes so the raw edge cooks off.
- Imli chutney (saunth): 100 ml pulp, 80 g grated jaggery, 1/2 tsp roasted jeera powder, 1/2 tsp dry ginger, 1/4 tsp kala namak, simmered 8 minutes until it coats a spoon. Our guide to gur covers picking a clean jaggery.
- Chaat and pani puri water: 1 tablespoon pulp per glass of spiced water.
- Imli ka amlana (summer drink): 1 tablespoon pulp, 2 tsp jaggery, a pinch of black salt and roasted jeera in 250 ml cold water.
If you’ve run out, amchur can stand in for dry dishes, and kokum for coastal curries, though neither has tamarind’s fruity depth. In a biryani pot the sour job often goes to aloo bukhara instead.
In many Punjabi and Hyderabadi homes, a small glass of imli and gur water was set out on hot afternoons, alongside the idea that sour-sweet drinks help the body cope with loo winds. In Unani thinking tamarind is counted among the cold and dry foods, which is why hakeems traditionally paired it with heat-season meals and warned people of a cold temperament not to overdo it. Ayurvedic texts describe it as sour (amla) and heating in effect, a reminder that the two systems don’t always agree. Treat both as tradition, not settled science. For how these temperaments work, see garam and thanda foods.
Myths and realities
“Imli is a laxative, so it’s good for constipation”
Ripe tamarind has plenty of fibre and fruit acids, and large servings do loosen some people’s stools. That doesn’t make it a sensible daily fix. If constipation is your issue, a steadier approach is covered in our isabgol guide.
“Imli thins the blood”
You’ll hear this from aunties, and it’s too vague to mean much. What’s reasonable to say is that anyone on blood-thinning medicine should mention regular tamarind drinks or supplements to their doctor, because tamarind has been discussed as possibly affecting how some drugs are absorbed. Normal cooking amounts in a curry are a different matter from glasses a day.
“Imli makes girls thin” or “imli dries up the blood”
Both are old scare stories told to stop children eating raw tamarind all afternoon. There’s no basis for either. The real reason to limit it is teeth and stomach, below.
Teeth: tamarind is very acidic. Sucking on raw imli or sipping imli water slowly bathes enamel in acid. Drink it with meals, rinse your mouth with plain water afterwards, and wait around half an hour before brushing, because brushing straight after acid scrubs softened enamel.
Reflux and ulcers: if you get heartburn or mouth ulcers, sour chutneys can make them sting and flare. See our note on acidity and heartburn.
Medicines: on blood thinners, aspirin taken daily, or diabetes medicine, keep tamarind at food amounts and raise any regular drink habit with your doctor. Imli chutney is mostly jaggery, so count it as a sweet if you manage blood sugar.
Pregnancy and breastfeeding: tamarind in ordinary food is part of many pregnancy diets and cravings. Keep it to food amounts, avoid concentrated supplements, and if sourness is worsening heartburn or nausea, ease off and talk to your midwife or doctor.
Kidney disease: tamarind is rich in potassium. If you’ve been told to limit potassium, keep to small cooking amounts and skip imli drinks unless your renal dietitian says otherwise.
Children: whole pods contain hard seeds that are a choking risk for small children. Keep pods and seeds away from under-fives.
See a doctor if you have ongoing diarrhoea, blood in stools, or signs of dehydration (very dark urine, dizziness, dry mouth) after eating a lot of tamarind.
Imli pulp questions from the kitchen
How do you make tamarind pulp from a block?
Break 50 g of block into small pieces, soak in 150 ml of hot (not boiling) water for 15 to 20 minutes, then squeeze and rub for two minutes. Push it through a strainer, give the leftover fibre a second 50 ml wash and strain again. You’ll get pulp about as thick as ketchup.
How long does homemade tamarind pulp last in the fridge?
About two weeks in a clean glass jar, as long as you always use a dry spoon. Frozen in ice-cube trays it keeps around three months, and each cube is roughly a tablespoon.
Should I boil imli or soak it?
Soaking in hot water gives a brighter, fruitier pulp. If you’re rushed, simmer the pieces on the lowest flame for 5 minutes, which loses a little brightness. Hard boiling for a long time tends to make it bitter.
Is imli safe in pregnancy?
In normal food amounts, it’s widely eaten and part of many pregnancy cravings. Avoid tamarind supplements and very large daily glasses. If sourness is worsening heartburn or nausea, ease off and mention it to your midwife or doctor.
Is imli bad for teeth?
It can be. Tamarind is very acidic, and sucking raw imli or sipping imli water slowly bathes the enamel in acid. Have it with meals, rinse with plain water afterwards and wait about half an hour before brushing.
Is imli good for constipation?
Large servings loosen stools for some people because of the fibre and fruit acids, but it isn’t a sensible daily fix. For regular constipation, steadier options like isabgol with enough water are kinder.
Can diabetics eat imli chutney?
Occasionally, in small amounts. Imli chutney is mostly jaggery, so count it as a sweet. Tamarind pulp in sambar or rasam is a different matter, since the amount per serving is small.
Does imli thin the blood?
That claim is too vague to mean much. If you take a blood thinner or daily aspirin, keep tamarind to food amounts and mention any regular imli drink to your doctor, as it may affect how some medicines are absorbed.
Why does my imli pulp taste bitter?
Usually it’s old, very dark stock, or pulp that was boiled hard for too long. Buy a block that feels slightly soft and tacky, use warm water and don’t overcook it.
Tamarind paste vs concentrate: are they the same?
No. Paste is close to homemade pulp. Concentrate is reduced, much stronger and often saltier, sometimes with added acid, so start with a small amount, taste, and build up rather than using the full quantity a recipe gives for pulp.
What can I use instead of tamarind?
Amchur works in dry dishes and kokum in coastal curries, though neither has tamarind’s fruity depth. A little lemon juice can stand in where extra liquid doesn’t matter.
Is imli okay for people with kidney disease?
Only in small cooking amounts, because tamarind is rich in potassium. If you’ve been told to limit potassium, skip imli drinks unless your renal dietitian agrees. Keep whole pods and seeds away from under-fives too, as the seeds are a choking risk.
