For oven instructions like 275–325°F, aim for a covered, barely-there simmer where bubbles rise occasionally and burst softly, roughly 180–195°F liquid temperature. Use a diffuser or the smallest steady flame, adding time rather than intensity. This gentle environment mimics a calm bake, tenderizing tough cuts and coaxing starches and aromatics into silky, integrated sauces.
To echo a 350–375°F bake, seek a medium flame that keeps oil shimmering and produces a consistent, modest sizzle without visible smoke. With a lid, interior air warms, approximating oven-like circulation. Expect slightly shorter crisping windows at the base and marginally longer interiors, so check early, then extend gradually until juices, texture, and aroma align perfectly.
