It is so much better to boil your own chickpeas for a salad, stew, keema curry, or croquette!
I love chickpeas. It is so much cheaper, tastier, and easier to boil them at home. I don't really like the smell while boiling though...
Cooking time might differ among pressure cookers, but it is the same cooking time as boiling soy beans. 250g raw chickpeas will end up as 600g boiled chickpeas.
