Marinade 101
The marinade is possibly the most useful tool in a cook’s repertoire besides a heat source. Good for imparting flavor and moisture into foods, a marinade can also act as a tenderizer for tough cuts of meat or starchy vegetables. The same key ingredient mediates both effects: acid. Chemically defined as any substance with a pH below 7, acids act to break down connective tissues within muscle. This makes the meat easier to cut and tear apart (i.e. more tender). It also increases the uptake of other components of the marinade like oils and spices, which bring moisture and flavor to the table. Although most traditionally a type of vinegar, any acidic liquid can be used in a marinade including wine, orange juice, or buttermilk.
By simply varying the type of acid and its accompaniments, a marinade can be used for almost any type of cuisine. For example, balsamic vinegar combined with olive oil, thyme, basil, and garlic makes a great Italian-style marinade. An Asian-style marinade can be made from soy sauce, orange zest, and sesame oil. Or you can combine them into a fusion dish. If made with dry ingredients, it transforms into a rub perfect for grilled steak or fish. Varying the marinating time further increases the versatility of this technique, allowing it to be used with both tender and tough cuts of meat. Marinades can also serve as excellent sauces after they are boiled to eliminate any traces of contamination from the raw meat.
Since an acid is the only crucial ingredient in a marinade there’s plenty of room for experimentation. This also means that marinades are very forgiving - so don’t be afraid to try something new!
