Instead of Vegetable oil or coconut oil

Sunflower oil
Use the same weight. Neutral flavour, works for all cooking; no change to the dish.
Groundnut oil
Use the same weight. Slightly nutty, good for Indian cooking; no real change.
Mustard oil
Use the same weight but heat it to smoking point first, then cool slightly. Pungent flavour will change the dish.
