Coconut Milk Technique: Cracking and Reducing
Origin
The separation of coconut cream into its fat and water components is a technique specific to Thailand and the surrounding regions where coconut curry pastes are used. The technique does not appear in the same form in Vietnamese or Burmese cooking, reflecting their different culinary architectures. Alford and Duguid document the technique throughout the Thai and Lao sections of the book. [VERIFY] Alford and Duguid's specific description of the cracking technique.
Description
Coconut milk — the liquid extracted from grated coconut flesh pressed with water — is not a single ingredient but a variable: the first pressing (coconut cream, thick and rich) and the second pressing (thinner coconut milk) behave differently in cooking and are used in different applications. The technique of "cracking" coconut milk — cooking the thick first pressing at high heat until the oil separates from the solids — is the foundation of all Thai and Lao curry-making and represents one of the most important techniques in the SE Asian cooking repertoire.
The Thread
Flavour Context
Cracking coconut milk is — Thermal Buffering — in reverse: instead of using fat to protect an ingredient from heat, the technique uses heat to liberate the fat from an emulsified liquid. The liberated coconut oil then acts as a high-temperature cooking medium that performs the Maillard and aromatic extraction functions impossible in the original emulsion.
