Rendering fat
Also searched as: rendering, rendering bacon, crispy duck skin, render fat
In short: Over gentle heat, fat melts out of skin and bacon. What remains is a thin layer that turns crisp.
Picture it
Like candle wax melting slowly and exposing the wick.

What happens
Fat sits locked inside cells. Over slow heat they melt and the fat runs out. If the heat is too high, the surface seals too early, and a thick, soft layer of fat stays under a dark crust.
Why it matters
Duck breast, bacon, pork belly and chicken legs need patience first and strong heat only at the end.
Rules of thumb
- Put it in a cold pan, then heat slowly.
- Score the skin first without cutting into the meat.
- Keep the rendered fat: ideal for fried potatoes.
