Bhuna was a throw-together to be honest. The usual spices and a bit of base at high heat to thicken it up.
The Bombay was par-boiled potatoes (pinch of turmeric and salt) left to cool. Then gently fry a finely chopped onion til softened - add mustard, nigella, fennel and onion seeds and a good tsp of aesafetida. Add potatoes, coriander leaf (I use dried) and a tablespoon or two of water. Add a splash of lemon juice before serving
