Citrus juice gives a clean, satisfying flavor to chicken, veal and fish. Use an herb that is compatible with the food you are marinating, such as thyme or tarragon for veal, sage for pork, dill or tarragon for fish. Let steaks, chops and fish fillets marinate for at least 1 hour in the refrigerator, or all day if you wish. Large cuts can marinate for 1 to 2 days.
1⁄2 cup olive oil
1⁄4 cup fresh lemon juice
1 garlic clove, minced
2 Tbs. finely chopped shallots or green onions
2 tsp. grated lemon zest
2 tsp. chopped fresh thyme, tarragon, dill or   sage, or 1 tsp. dried herb of choice
1⁄2 tsp. salt
1⁄2 tsp. freshly ground pepper
In a small bowl, whisk together the olive oil, lemon juice, garlic, shallots, lemon zest, thyme, salt and pepper. Use immediately or refrigerate in a tightly covered jar for up to 2 days. Makes about 1 cup, enough for 2 to 3 lb. veal or pork chops, steaks or fish fillets.
