Brining is basically giving your turkey a saltwater spa day. You soak the bird in a solution of salt, sugar, and maybe some herbs for 12 to 24 hours. Sounds weird? It should. But it works.
The science is simple: salt and water get cozy and march into the turkey’s cells. Once inside, they physically change the protein structure, making it harder for juices to escape during cooking. Think of it like a security guard locking the doors on a juice-filled bank vault.
