One of the many members of the prolific and tasty mint family, it is closely related to marjoram , the only difference being that oregano is more pungent and less sweet.
Oregano is used widely in Mexico and the Southern Mediterranean-particularly in Italy and Greece.
This herb first gained popularity in the United States after Word War II ended and soldiers returned from Europe with a taste for Mediterranean cooking. Mediterranean oregano, which is the most commonly found in the U.S. as well, is somewhat milder than the Mexican variety. This bold herb enhances most meats, particularly lamb, beef and fish. It also livens up beans, eggs and many vegetables, including cabbage, eggplant, squash, corn and avocados. To make a delicious basting sauce, melt some butter in a saucepan, stir in some crushed garlic, chopped oregano leaves, lemon juice, and a little salt and pepper.
