Brining, dry-brining and osmosis: juicier meat explained
Salt draws moisture out first (osmosis), then dissolves in it and diffuses back in. Inside, salt partly dissolves muscle proteins so they hold more water while cooking: juicier, more seasoned meat.
Wet brine
A common lean-meat brine is about 5-6% salt by weight of water (roughly 50-60 g salt per liter), for an hour or two for chops and several hours to overnight for whole poultry. Different salts measure very differently by volume, so weigh it.
Dry brine
Salt the meat (often about 1% of its weight) and leave it uncovered on a rack in the fridge for hours to a day or two. Skin dries for better browning. No bucket needed.
Safety
Brine in the refrigerator at 40°F or below, never at room temperature, and discard used brine. Don't rinse raw poultry. Cook to the safe minimum internal temperature.
Ask your bot about the science
Explain brining & osmosis in plain English for a home cook, with one kitchen experiment I can do to see it, and how it applies to [dish].
Give temperatures in °F and °C and say if they are approximate.Where these facts come from
