This Bengali recipe of Bhapa Sheem Chorchori is an easy vegan mixed vegetable curry made using flat beans, tomatoes, and a touch of pungency from mustard seeds. This is one of those hundreds of easy vegan lunch recipes that are often made for everyday cooking. Shim Chorchori is perhaps the easiest of all as all you have to do is dump everything in a pressure cooker and wait till it whistles. That's it.
Prep the flatbeans or shim by cutting off the tips and pulling off the string from the sides. Now cut them into pieces of an inch of thickness.
Grind the mustard seeds and the wild celery seeds into a coarse paste using a couple of tablespoons of water.
Put all the ingredients including the freshly ground paste (except the coriander leaves) in the pressure cooker along with ¼ cup of water. Mix everything together.
Close the lid of the pressure cooker and allow it to whistle 2-3 times on high heat before turning the heat off. Let the cooker cool down on its own.
Open the lid and check if the flatbeans have been cooked. She should be soft but not an absolute mush. Adjust the consistency of the gravy by boiling it further.
Once done, sprinkle the finely chopped coriander leaves on top. You may also drizzle some mustard oil if you do not mind the pungency.
