Epsom Salt, while primarily known for its therapeutic uses, is sometimes used in small amounts in cooking and food preservation. In a 100g package, it can be utilized for brining meats, as it helps retain moisture, or for pickling, enhancing the crispness of vegetables. However, it’s essential to use Epsom Salt sparingly and ensure it's food-grade, as excessive consumption can have laxative effects. Always check for proper use in recipes!
