What You Need to Know
The dish employs sequential layering to control heat penetration: dense squash at the bottom (high pectin content requiring 90+ min breakdown), mid-layer eggplant (with phenolic compounds that oxidize brown), and bitter melon on top (preserving its cucurbitacin bitterness). Fermented fish (bagoong) provides endogenous proteases (cathepsin L, 40-60°C optimal) that tenderize vegetable cell walls.
The earthen pot (palayok) creates a thermal gradient, with the bottom reaching 95°C while the top stays at 70°C, allowing simultaneous softening and bitterness retention. Traditional cooks test doneness by pressing the squash layer - proper breakdown should show 'cracked but not mushy' cell structure.
