Kidney

Use the same weight; split, core and rinse well, then cook quickly or they toughen.

Use the same weight, sliced; stronger flavour and cooks faster, so add 5 minutes later.

Use the same weight, chopped; cooking time varies, so simmer until just tender.

Use the same weight, halved; cook 10-12 minutes and do not crowd the pan, or they stew.

Use cooked chickpeas at about the same weight; simmer 10 minutes to absorb the gravy.

Use 60-70% of the weight, cubed; add 10 minutes before the end so it stays soft.
