Description
Pho broth is a clear, umami‑rich stock made by simmering beef bones and spices for hours.
Technical
During prolonged simmering, collagen in the bones denatures and dissolves into gelatin, while amino acids and nucleotides release flavor. The brief toasting of spices liberates essential oils, and controlled acidity from fish sauce and lime stabilizes the pH, preventing excessive Maillard reactions.
