Do keep a thin layer of water in the pan/griddle when cooking meat on the stove. This helps keep the meat below the boiling point, which avoids the production of amines. Do eat white meat (poultry), rather than dark meat, it's a bit safer. Skinless breasts are ideal. Do avoid the fat, and the drippings that collect during cooking.
