Challun is a traditional Bengali shrimp paste made with tiny freshwater Shrimp, garlic, dried red chillies, and mustard oil. Popular in rural Bengal, it has been enjoyed for generations as a fiery accompaniment to hot steamed rice. Unlike the fermented shrimp pastes used in Southeast Asian cooking, Challun is freshly cooked and ground into a spicy paste that can be refrigerated or frozen for later use.
The story I have heard in my in-law’s place it that the fishermen would carry this Challun and some rice when they went fishing early in the morning, and they could happily finish a whole plate of rice with a little bit of Challun. Challun is a shrimp paste, but it is different from the Asian shrimp paste which is used in Asian cooking, that is fermented, and there are no chillies but Challun is more like a pickle, it can be kept in normal temperature for 3 or 4 days and in the fridge even longer. I usually freeze it, and since there is no water in it, I can take it out and eat it without defrosting.
We use the very small freshwater shrimps ( Kucho Chingri) in this recipe.They are available rather cheap and easily in the small towns and villages in Bengal, whereas in big cities like Delhi it is rare. The tiny tiny shrimp are difficult to clean as they are so small, plus it is a long and tedious process too, if you want to shell them. This recipe is the only way I have seen it being used.
First the shrimps are just washed very thoroughly to remove sand and other dirt. After the water drains out, it is fried in mustard oil with dry red chillies and garlic and then ground to a paste in a blender, or mixer. It turns out to be very hot due to the chillies.

These are the tiny shrimp. I found a few other types of small fish mixed with the shrimp, but did not discard them used them too.
You can also use the smallest shrimps available to you. I have never used the frozen ones but it needs to defrost completely before frying, because there might be too much water and so make it difficult to fry.
These are the ingredients you will need.


First heat the oil and fry the garlic pods.
Then add the chillies and fry those too.


Keep these aside in a dish.
Then in the same oil fry the shrimp


It should look like this when fried.
The chillies, and garlic and shrimp are fried and now it needs to cool down


Once it cools down, transfer the fried shrimp, garlic and chillies to a grinder, add some salt and grind to a paste. Taste and adjust the salt.
This recipe is one of my favourites. It a very easy and in expensive to make, and is packed with flavour. It can be stored or frozen.
- Refrigerator: up to one week.
- Freezer: up to three months.
- Use a clean, dry spoon every time.

Challun (Bengali Shrimp Paste) | Traditional Chingri Pickle Recipe
Ingredients
Equipment
Method
- Wash the shrimp thoroughly. Put them in a colander and wash under running water so that there is no sand in it. Also sort out any twigs.
- Peel the garlic.
- If you want to make the Challun little less hot, remove the seeds from the dry chillies before frying them. I have kept the seeds, you can see the seeds in the photo because they didn’t grind in the grinder.
- Heat the mustard oil in a kadai ( wok) or pan
- Fry the garlic first till they are a little brown at the edges
- Add the chillies and fry them too, till a bit brown.
- Remove the garlic and the chillies from the pan with a slotted spoon and keep aside.
- In the oil that it left in the kadai fry the Shrimp till they are pink and crisp
- Once the shrimp and garlic and chillies and cool, put them in a strong electric grinder, add some of the salt and also if there is any oil left in the kadai.
- Grind to a paste. It may not grind smoothly in one go so you will have to remove the lid of the grinder and stir the mixture. You can add a little more oil if necessary.
- Taste to see if the salt is enough before taking the challun out of the grinder and serving.
- It is best eaten with cooked/steamed rice.
Notes
- Wash the shrimp several times to remove all sand.
- Don’t burn the garlic.
- Let everything cool before grinding.
- Add a little mustard oil if the paste is too dry.
- Freeze in small portions.
