What technique is used to impart flavor into a protein through the use of acid and aromatics?

The technique of marinating is used to impart flavor into a protein by combining it with an acid (such as vinegar or citrus juice) and various aromatics (such as herbs, spices, and garlic). The acid helps to tenderize the protein while also infusing it with the combined flavors of the ingredients in the marinade.

This process usually requires the protein to sit in the marinade for a period of time, allowing the flavors to penetrate and enhance the overall taste of the dish. The incorporation of aromatics not only adds depth and complexity to the flavor profile but also can help to mask any undesirable tastes inherent to some proteins.

In contrast, brining refers to soaking a protein in a saltwater solution, focusing primarily on moisture retention and flavor enhancement through salt rather than the infusion of flavors from aromatic ingredients. Braising is a cooking technique that involves slow-cooking in a small amount of liquid after initial searing, while poaching is a method of cooking in simmering liquid. Neither of these techniques primarily emphasizes the combination of acid and aromatics for flavor infusion as marinating does.
