Did you know that garlic is a member of the onion family? Allium sativum is its Latin name, and it’s related to shallots, leeks, and chives. It’s native to central Asia but grows just about everywhere now. Garlic has been used as both food and medicine for more than 7,000 years.

What You Need

-Airtight Storage Container
-Extra Virgin Olive Oil or Canola Oil
-Cheesecloth or coffee filter
-Paprika (optional)

To simplify the process, start with peeled garlic cloves. You can also use unpeeled garlic, but it will take a little longer to prepare. Place garlic in a clean and dry airtight storage container. Fill the container with enough oil to completely cover the garlic cloves. For a 1-pint (470 ml) jar of garlic, you will need about 1 cup (240 ml) of oil. Add paprika for color, if desired.

Seal the container tightly and store in a cool, dark place for up to 4 months. Check the garlic occasionally to make sure it is covered with oil and add more if necessary.

The Process

The process is simple. Start by peeling the garlic cloves and then gently crushing them. You can do this with a mortar and pestle, or by using the flat side of a knife to press down on the cloves. Next, heat up your oil of choice in a small saucepan over low heat. Add the garlic to the oil and stir gently until all of the cloves are coated. Allow the mixture to simmer for a few minutes, then remove from heat and let it cool. Once cooled, transfer the garlic and oil to a clean glass jar and store in the refrigerator for up to two months.
