Methods to consider when storing garlic include freezing the garlic by wrapping it in a plastic bag and drying it in the oven. It's also possible to store garlic in oil.
When freezing garlic, chop it finely first and wrap tightly in a freezer bag. Grate the garlic as needed. Unpeeled garlic cloves can be frozen as well. Just remove the cloves as they are needed. Freezing garlic puree is a third option and involves blending two parts oil to one part garlic. Freeze the puree immediately. It stays soft in the freezer and can be used as needed.
When drying garlic, use fresh and firm garlic cloves. To start, peel the garlic cloves and cut them in half lengthwise. Proceed to dry the cloves in an oven heated at 140 degrees Fahrenheit for two hours. Next, reduce the heat to 130 degrees Fahrenheit until the garlic is thoroughly dry or crisp. Powdered dry garlic can be made by blending in a food processor.
When considering storing garlic in oil, submerge the peeled garlic cloves in the oil, store in the freezer and use as needed. After adding the garlic to the oil, do not store the mixture at room temperature as it can breed food-borne illnesses.
