Apple cider vinegar does the heaviest lifting in this pot by supplying acetic acid, which lowers the pH of the cooking water. This mild acidity helps break down collagen within the connective tissue of the chicken bones, hydrolyzing tough structural proteins into water-soluble gelatin that gives the final liquid its rich mouthfeel. Cooking bones at high temperatures under pressure accelerates this hydrolysis far beyond traditional simmering methods.
Thermal energy inside the sealed chamber forces moisture deep into the bone matrix, rendering marrow fats and minerals into the surrounding liquid. Aromatics like onion and garlic contribute sulfur compounds and free amino acids, building savory depth through Maillard-adjacent reactions during the prolonged heat phase. Ginger introduces zingiberene, an enzyme that imparts a clean, sharp finish to offset the heavy gelatin.
Fish sauce supplies free glutamates, synergizing naturally with the nucleotides released from the chicken meat to amplify umami perception without leaving a discernible fishy taste. When the 100-minute high-pressure cycle concludes, dropping the unit to low pressure for an additional 60 minutes maximizes mineral extraction from the calcified matrix.
Allowing the pressure to release naturally prevents violent boiling that can emulsify fats and cloud the broth with particulate matter. Straining the warm liquid through a fine mesh yields a clear stock that solidifies into a gelatinous gel upon chilling in the refrigerator.
