I read few recipes for making broth or stock using pressure cooker. If I add more water, do I need to add more cooking time? For example, a recipe like this: - 1/2 kg of chicken wings - 1 onion - 1 leek - 8 garlic cloves - 3 star anise - 2 liter water - 30 minutes pressure cooking, start the timer after the high pressure reached Now, I want to make for 3 liter water, for more person. Do you think that I must add more pressure cooking time? I think I must add half more portions for other ingredients as well: - 3/4 kg of chicken wings - 1,5 onion - 1,5 leek - 12 garlic cloves - 4,5 star anise - 3 liter water But, is it then the same 30 minutes or .... 45 minutes?
