What You Need to Know
During braising, heat denatures collagen triple helices, hydrolyzing them into soluble gelatin peptides that, upon cooling, form a three‑dimensional protein network trapping water and fat. The resulting aspic solidifies at around 21 °C, giving the dish its characteristic springy texture. Concentrations of 2–3 % gelatin are sufficient to create a stable gel matrix.
