Can you use brine more than once?

Yes, you can reuse brine, but its effectiveness diminishes with each use. The first use extracts flavors and moisture from the food, and subsequent uses may not impart as much taste. It's important to strain and refrigerate the brine after use, and be mindful of food safety, as bacteria can grow in reused brine. Generally, it's best to limit reuse to one or two times and to discard it if it shows any signs of spoilage.
