What You Need to Know
Gelatinization of potato starches (Solanum tuberosum Andigenum group) at 58-65°C creates viscosity, while slow hydrolysis of fish connective tissues (mainly type I collagen) releases glycine and proline. Maillard reactions between onion sugars and seafood proteins develop depth.
The 'second boil' technique (adding dairy after initial simmer) controls protein coagulation. Coastal versions use sea urchin roe for enzymatic tenderization, while highland variants employ freeze-dried potatoes (chuño) for thicker texture.
