Make Aam kasundi recipe – Instant Bengali mango mustard sauce recipe at ease (without long fermentation) with step-by-step photos.
What is Aam kasundi ?
Aam kasundi is a bengali style mango mustard sauce made with green mango or raw mango (kacha aam/কাঁচা আম), mustard (shorshe/সর্ষে in Bengali) & some spices. However, this mango kasundi is a twist of the tangy raw mango & spicy mustard sauce recipe. Generally, Kasundi (bengali mustard chutney) is used as a bengali snack dipping sauce, this aamer kasundi (mango mustard sauce) does the same, however, one can eat this tangy chutney with rice or roti too.

Aam kasundi contains a smooth paste of raw mango with mustard seeds & vinegar, spiced up with dry roasted whole cumin, red chill and bengali five spices blended form.
Green Mango – Choose quite hard green mangoes from the market. Hard mangoes are still raw from the inside and good for making this sauce. Whereas comparatively soft green mangoes can have yellow pulp not good for making kasundi and not good for longevity as well.
Mustard seeds – Here I used black mustard seeds, you can use half a half of black and white or yellow mustard seeds too. Don’t use readymade store bought mustard seeds powder that can make this sauce bitter.
Vinegar – Vinegar is one more important ingredient in making plain kasundi or aam kasundi. ➊ Firstly, Vinegar helps in making a smooth paste of mustard, ➋ secondly, vinegar acts as a stabilizer or preservative in this sauce & Lastly, vinegar removes the bitterness of mustard. ➌ Though vinegar adds a little more tanginess to this sauce however the addition of salt & sugar easily balances it.
Cumin seeds & dry red chilli – Cumin seeds and
This raw mango-flavoured spicy & tangy mustard sauce goes perfect with any bengali snacks as a dip. This mango-mustard sauce also goes well with rice & dal or rice & shaak bhaja. Even this sauce also can be used in making different bengali recipes.
