What You Need to Know
Sichuan stir‑frying at 200–250 °C triggers a Maillard reaction that caramelizes surface sugars and denatures proteins, while the hydroxy‑α‑sanshool in Sichuan pepper imparts a numbing sensation. Cantonese braising at 80–90 °C for 1–2 h hydrolyzes collagen into gelatin, tenderizing pork belly and enriching the broth with umami glutamates. Cantonese steaming at 100 °C preserves moisture, prevents protein denaturation, and retains volatile aromatics such as ginger and scallion.
