Garlic is widely used around the world for its pungent flavor, as a seasoning or condiment. Depending on the form of cooking, the flavor is either mellow or intense. It is often paired with onion, tomato, or ginger. The parchment-like skin is much like the skin of an onion, and is typically removed before using in raw or cooked form. An alternative is to cut the top off the bulb, coat cloves of garlic by dribbling olive oil(or other oil based seasoning) over them and roast them in the oven. The garlic softens and can be extracted from the cloves by squeezing the (root) end of the bulb or individually by squeezing one end of the clove.
Oils are often flavored with garlic cloves. Commercially prepared oils are widely available, but when preparing garlic-infused oil at home, there is a risk of botulism if the product is not stored properly. To reduce this risk, the oil should be refrigerated and used within one week. Manufacturers add acids and/or other chemicals to eliminate the risk of botulism in their products.[5]
In Chinese cuisine, the young bulbs are pickled for 3–6 weeks in a mixture of sugar, salt and spices. In Russia and the Caucasus, the shoots are pickled and eaten as an appetizer.
Immature scapes are tender and edible. They are also known as 'garlic spears', 'stems', or 'tops'. Scapes generally have a milder taste than cloves. They are often used in stir frying or prepared like asparagus. Garlic leaves are a popular vegetable in many parts of Asia, particularly Chinese, Vietnamese, Cambodian, Laotian and Korean cuisines. The leaves are cut, cleaned and then stir-fried with eggs, meat, or vegetables.
Garlic is essential to several Mediterranean dishes. Mixing garlic with eggs and olive oil produces aioli ("garlic and oil" in Provençal). The Spanish variant does not use eggs. Garlic, oil, and a chunky base produce skordalia (from the Greek and Italian names of garlic). Blending garlic, almond, oil and soaked bread produces ajoblanco (ajo blanco is Spanish for "white garlic"). Le Tourin is a French garlic soup.
Medicinal use and health benefits
Garlic has been used as both food and medicine in many cultures for thousands of years, dating as far back as the time that the Egyptian pyramids were built. Garlic is claimed to help prevent heart disease including atherosclerosis, high cholesterol, high blood pressure, and cancer.
Animal studies, and some early investigational studies in humans, have suggested possible cardiovascular benefits of garlic. A Czech study found garlic supplementation reduced accumulation of cholesterol on vascular walls of animals.
Another study had similar results, with garlic supplementation significantly reducing the placque in the aortas of cholesterol-fed rabbits.
Another study showed that supplementation with garlic extract inhibited vascular calcification in human patients with high blood cholesterol.
