How to Fry Onions for Biryani (Crispy Birista)
Even slices. Steady heat. Golden, not black.
Birista is thinly sliced onion fried until deep golden and crisp. It flavours biryani, korma and pulao and is layered on top for sweetness and crunch. Onions burn fast at the end, so the key is even slicing, medium heat and lifting them out one shade before you want them.
