Did you know...?

  • Garlic is part of the allium family that includes onions, leeks, scallions and shallots.
  • Garlic is not pollinated; it is grown from cloves.
  • Colloquial names for garlic are Russian penicillin, Bronx vanilla and Italian perfume.
  • Garlic was used in the three major healing systems: Indian Ayurveda, traditional Chinese medicine and European medicine.
  • An annual garlic festival is held in Gilroy, Calif., every year.
  • Koreans are the leading consumers of garlic, eating 22 pounds per person per year, while Americans eat 2.5 pounds.
  • Japanese cuisine does not use as much garlic as other Asian cuisine. Instead, garlic is used for its potential medicinal value.

Folklore Fun (NOT Facts!) about Garlic

  • Garlic is a folk preventive against monsters, including vampires.
  • Athletes have used garlic to bring good luck in competitions.
  • During the plague, garlic was used to ward off disease and was carried in posies.
  • Love spells used garlic to attract one’s beloved.

Preparing Fresh Garlic

  • To quickly peel garlic, heat it in the microwave for a few seconds. The peel will magically loosen.
  • Loosen the paper-like skin from garlic by laying the clove under the flat side of a large knife. Tap the knife once, then slice off the stem end before mincing.
  • Chop, mince or crush garlic using a sharp knife. The finer you chop the garlic, the more flavor you will release.
  • Once you have a peeled and stemmed garlic clove, smash it more thoroughly against a cutting board, then mince the smashed garlic into bits.
  • Tools of the trade: use the latest gadget called a garlic rocker or the traditional garlic press to mince garlic.
  • Make garlic paste by mashing peeled and stemmed garlic cloves with a little salt with the end of your kitchen knife on a cutting board; alternatively, mash garlic cloves with salt in a mortar with pestle.
  • Do not wash garlic cloves until ready to use, or the moisture will promote mold growth.

Remove the smell of garlic from your hands by rubbing them on a cut lemon, or wet hands and rub them on stainless steel.

Storing Fresh Garlic

  • To store fresh garlic, keep the cloves intact with the bulb head and store in a cool, dry, dark location in a mesh bag or in a garlic keeper.
  • Store in a well-ventilated area, and do not seal in plastic.
  • Garlic may keep its quality for three to six months in the right conditions or in the refrigerator if your kitchen or other storage area is very warm.
  • If the cloves begin to shrivel or sprout, that does not necessarily mean the garlic is bad but that it is no longer at its peak quality. The green-colored sprout may be bitter, so remove before preparation.
  • Garlic can be frozen by placing the whole bulb, individual cloves or peeled, chopped cloves in a single layer in a plastic freezer bag. Or try flash freezing by placing whole or chopped cloves on a parchment-lined tray and placing the tray in the freezer. After they’re frozen, seal the frozen garlic in a freezer bag. Use frozen garlic within three to four months for best flavor.

Adding Garlic to Favorite Recipes

  • Crush or mince fresh garlic and add to soups, stews or chilis.
  • Add minced garlic to your favorite salad dressing recipe, or simply add to a bottled dressing.
  • Make a simple vegan aioli by adding to an electric blender equal parts plant-based milk and olive oil with minced garlic. Season with prepared mustard, red wine vinegar, fresh or dried herbs, and salt and pepper. A few drops of pure maple syrup may be added for a hint of sweetness.
  • Add sliced garlic to any stir-fry recipe or minced garlic to a stir-fry sauce.
  • Add fresh garlic, garlic powder or garlic flakes to your favorite spaghetti sauce, sloppy joes, taco meat or
    jarred salsa.
  • Garlic may be added to ready-to-eat deli salads or cowboy caviar.
  • Dip fresh slices of French bread in extra virgin olive oil infused with freshly minced or pressed garlic, along with red wine or other aromatic vinegar, minced parsley, dried red pepper flakes and sea salt. Marinate cold boiled shrimp with this mixture for an appetizer.
  • Garlic powder may be added to any gravies or sauces.
  • Throw whole, unpeeled garlic cloves into any homemade stock along with other vegetables; strain, then use in recipes or freeze in batches.
  • Use whole, unpeeled or peeled garlic cloves along with mirepoix (celery, carrot, onion) and whole chicken to make chicken soup or broth. Strain to freeze broth in 1- to 2-cup containers.
  • Use smoked garlic during grilling season. If you don’t have a smoker, ask a neighbor to smoke some for you. Roast smoked garlic or use as you would regular garlic.

Safety Warning for Garlic-flavored Oil

Do not store garlic in oil at room temperature. Garlic may contain Clostridium botulinum spores from the soil. In the right conditions, the spores can produce the deadly botulism toxin. Therefore, if you flavor oil with garlic, store the mixture in the refrigerator or freezer. Use the refrigerated mixture within a week.

Research Notes

Garlic (Allium sativa L.) is an aromatic herb used in cooking food as well as in traditional remedies in medical applications. It possesses numerous biological properties for human health: anticarcinogenic, antioxidant, anti-inflammatory, antidiabetic, renoprotective (kidney), cardioprotective, antiatherosclerotic, antibacterial, antiviral, antifungal and antihypertensive, among others. Garlic stimulates the production of nitric oxide and increases blood flow.

Garlic is rich in sulfur-containing plant components, namely alliin, allicin and ajoene, along with flavonoids such as quercetin. Garlic comes in many forms: raw, cooked, powder, granules or flakes, oil, and aged garlic extract dietary supplements. Activate garlic’s potency by smashing a raw garlic clove and allowing it to sit for a few minutes before ingesting or cooking.

Basic Garlic Butter

Garlic Butter

½ c. softened unsalted butter
1-2 tsp. minced fresh raw garlic, or more to taste
Salt and pepper to taste

Blend butter and minced garlic with a spoon or mash with a fork. Transfer to a tightly sealed jar or plastic container and store in fridge for up to two weeks. When ready to use, let soften at room temperature to make garlic bread or toast, or spread on meat, mix with mashed potatoes or melt over steamed vegetables. If using salted butter, do not add extra salt. If cooking with garlic butter, put a little vegetable oil in the pan first, or the butter and garlic may burn easily.

*Fresh Herbs Option

In addition to butter, garlic, and salt and pepper, add the following:
2 Tbsp. finely chopped fresh parsley, fresh basil or other fresh herb of choice
2-3 tsp. fresh lemon juice

Blend all ingredients and form into a roll. Wrap tightly in plastic wrap and freeze up to six months. Slice and use as desired.

Basic Roasted Garlic

4 whole garlic bulbs, unpeeled
2 Tbsp. olive, canola or other oil
¼ tsp. salt

*Optional seasonings:
1 tsp. Italian seasoning, crushed between palms of hand to release oils
½ tsp. black pepper
¼ tsp. paprika

Preheat oven to 375 F. Peel outer layers of garlic but leave the bulb intact. It’s OK if some of the tighter peels on garlic cloves remain. Cut ¼ to ½ inch off the top of garlic bulb/cloves, still leaving the bulb intact. Place the garlic bulbs cut-side-up on a large piece of foil; drizzle olive oil over each bulb and sprinkle with salt. Wrap garlic bulbs in foil and place on a baking sheet. Roast until the garlic is soft and has a light caramel color, about 45 minutes. Allow to cool before squeezing garlic out of bulbs, from bottom to top. Mash the cloves in a small bowl with a fork until they are the desired consistency. Use in recipes, such as Mashed Potatoes with Cauliflower included in this guide, or as a spread.

*Optional seasonings: After mashing the cloves in a small bowl, add optional seasonings and stir. Add to salad dressings, sandwiches or meat dishes.
