The best time to salt meat before grilling depends on the thickness of the cut and the desired outcome. For thinner cuts, salt just before grilling; for thicker cuts, salt at least 40 minutes beforehand, or even overnight.
Salting meat draws out moisture initially. However, given enough time, the salt will dissolve into the moisture, creating a brine that is then reabsorbed into the meat. This process, known as osmosis, seasons the meat more deeply and helps to tenderize it.
Here's a breakdown:
If you salt meat less than 40 minutes before grilling, the salt will draw out moisture, but the meat won't have enough time to reabsorb it, resulting in a drier final product.
Use kosher salt for salting meat. Its larger crystals distribute more evenly and dissolve more readily than table salt, leading to more consistent seasoning. Avoid using iodized salt, as it can impart a metallic taste.
