Cumin (Bizari / jeera (also "jira"))
A staple warm spice on the Kenyan coast: whole or ground seeds are dry-toasted or bloomed in hot ghee/oil to build the base of pilau, biryani, samosa filling, mbaazi and meat curries. On keto it seasons fatty stews, roast meats, cauliflower "pilau" and eggs, and can be steeped as jeera water.
Traditionally used to ease digestive complaints such as bloating, gas and indigestion, commonly taken as a warm cumin-seed infusion (jeera water) after heavy meals. In folk practice it is also taken to stimulate appetite. These are traditional uses, not proven treatments for any condition.
Essentially a free seasoning on keto: the small culinary amounts used add negligible carbohydrate, and its warm, earthy flavour pairs well with the fats (ghee, coconut, tallow) that carry keto dishes.
