Resting Meat
Letting cooked meat sit before slicing so juices redistribute instead of running onto the cutting board.
During cooking, muscle fibers contract and squeeze juices toward the center. If you slice immediately, those juices pour out. Resting (5-10 min for steaks, 30+ min for brisket) lets the fibers relax and reabsorb the moisture. Tent loosely with foil — wrap too tight and you'll steam the crust off.
Why it matters
It's the cheapest, easiest upgrade in cooking. Don't skip it.
