What You Need to Know
The gentle heat denatures muscle proteins while the surrounding fat creates a sealed, uniform environment that limits moisture loss. Collagen begins to solubilize into gelatin around 70 °C, improving mouthfeel and juiciness. Keeping the temperature well below the fat’s smoke point (<190 °C) prevents oxidative rancidity and off‑flavors.
