Thai soup can taste almost electric when it is right. One spoonful is bright with lime, warm with chiles, savory with fish sauce, fragrant with lemongrass, and still somehow clean enough to make room for the next bite.

A good Indonesian soup rarely tastes flat. Even the simplest bowl has movement: a fragrant spice paste, a bright squeeze of lime, a salty finish, fresh herbs, and often a crunchy topping. The broth may be clear, creamy with coconut milk, earthy with keluak, or sour from tamarind and vegetables.
