Can this be made without a pressure cooker? The adaptation requires shifting from sealed steam to an open pot. Standard stovetop preparation works well when handling coconut milk bases. Simmer chicken and aromatics gently over medium-low heat for twenty minutes. High heat causes full-fat coconut milk to curdle and split into an oily layer. Watch the liquid closely during the simmer stage.
Pressure cookers force flavors into meat rapidly. Stovetops require time instead. Cut poultry into uniform pieces under one inch to ensure even cooking during a standard simmer. Keep the pot uncovered or partially ajar. Stir frequently to prevent coconut solids from scorching on the bottom of the pan. Stainless steel pots demand more attention than heavy-bottomed Dutch ovens.
Frozen lemongrass and dried kaffir lime leaves behave differently than fresh produce. Fresh stalks release volatile oils immediately upon bruising with the back of a knife. Frozen chopped lemongrass lacks these volatile surface oils. Double the volume of frozen lemongrass to match the aromatic output of one fresh stalk. Soak dried lime leaves in warm water for ten minutes before slicing to restore pliability and release trapped citrus notes.
