Press the tofu, if you haven't already, and then tear it into bite-sized pieces. You can also cube the tofu if you like. Add the tofu to a bowl along with the yogurt, toss well to coat. Then, mix all of the dry spices and the cornstarch in a small bowl, and sprinkle all over the tofu, drizzle the mustard oil if you're using it, and then toss well to coat the tofu.
Heat a skillet over medium-high heat, and add the teaspoon of oil, and once the oil is hot, spread the tofu onto the skillet. Let the tofu sit undisturbed for 2 to 3 minutes, so that it can brown on the bottom, and then dislodge the bottom and flip to brown the other side. Drizzle on another teaspoon of oil, if needed, to help the tofu brown. Once the tofu is golden brown on most of the edges. Remove the tofu from the skillet.
Reduce the heat to medium, and add the 2 teaspoons oil to the same skillet. Once the oil is hot, add the cardamom pods, cloves, cinnamon, dried chilies, and bay leaves, and mix really well. Cook those for 15 to 30 seconds, until the bay leaves change color. Then, mix in the onion and 1/4 teaspoon of the salt. Let the onion sit undisturbed for 2 to 3 minutes, then stir a little bit and let it sit for another 1 or 2 minutes again. Increase the heat to medium-high, and continue to cook until the onion starts to char and caramelize in places. Add a splash of water here and there to help the onion brown evenly. Make sure to stir frequently, since we are cooking at a pretty high heat, and you don’t want the onion to burn. If your pan is not heating up enough, then you can increase the heat to high. Once half of the onion is starting to char, reduce the heat a little bit to medium-high or medium, and continue to cook. You can also cover the pan with a lid at this point to help the onions cook evenly without drying out. 7-9 minutes
Once most of the onions are golden brown, add the ginger garlic paste, 2 to 3 tablespoons of water, and all of the ground spices to a small bowl and mix really well. Add this mixture to the pan with another splash of water, and mix the mixture into the onion. Cook for about half a minute, then mix in the tomato puree. After about another half a minute, stir in the nondairy yogurt and 3/4 cup to 1 cup of water, then cover with the lid, and reduce the heat to medium, if it was higher. Continue to cook for about 10 minutes to cook all of the spices and allow the flavors to meld. The sauce will thicken a little bit and pick up flavor from the onion. Stir once in between, add 1/2 to 1 cup of water or stock, depending on how thick or how saucy you want your finished dish to be.
Add the crisped up tofu, the chilis, and the remaining salt to the pan, toss lightly, and cover with the lid again. Reduce the heat to medium-low, and let the tofu simmer in the sauce for 10 to 15 minutes. At the 10-minute mark, taste and adjust the salt and flavor. You can also add more water or stock if the sauce is thickening too much. Then, either simmer for a few more minutes for a thicker sauce that clings to the tofu or switch off the heat if you want it saucier. Serve garnished with the cilantro and lemon juice and with some naan, flatbread, rice, Pulao, or luchi, which is a fried Bengali flatbread.
Store in an airtight container in the refrigerator for up to 4 days; reheat gently on the stovetop with a splash of water or oil to restore sauce consistency.
Kosha mangsho is savory and aromatic with warm spice notes from cardamom and garam masala, balanced by Kashmiri chili powder's mild heat and depth. The onion sauce caramelizes into a rich, slightly thick base.
Pressing tofu for at least 15 minutes removes excess moisture so it absorbs the curry sauce better and browns more evenly when cooked.
Yes, regular yogurt works as a tenderizer and adds creaminess; use the same amount. Non-dairy yogurt keeps the dish vegan.
Cornstarch is optional and thickens the sauce slightly for a glossier, more clingy coating on the tofu if you prefer a thicker curry.
Mustard oil is optional but traditional in Bengali cooking and adds a distinctive peppery note; neutral oil works if unavailable.
