Onion raita is frequently made in home for biryani or pulav and is very simple. This is the same I make to go with veg biryani, chicken biryani etc. eating more oily food like biryani can cause over heat in body. To maintain the body heat at equilibrium and to avoid digestion problems, curd is used along with onions. It is healthy, tasty and also easy to make. It is everyone’s favorite.
