For Karela shape Nimki...Take refined flour in a big mixing bowl followed by cumin seeds, carom seeds, salt, black pepper, and oil. Mix everything really well.
Add water in small portions to the flour and knead stiff dough. Dough should be harder than required for making pooris. Cover and leave the dough on one side for 15 to 20 minutes to set.
Later, knead the dough a little and divide it into medium lemon size lumps. Take a lump and roll it out into 6 to 7 inch diameter round and thin poori.
