reserving garlic for up to six months can be incredibly useful, especially if you like to buy in bulk or harvest your own. Here’s a simple trick to extend the life of your garlic:

Preserving Garlic in Oil

1. Peel and Chop: Start by peeling the cloves of garlic. You can chop them if you prefer minced garlic for easier use later, or leave them whole.
2. Sterilize Jars: Ensure that the jar you are using to store the garlic is completely sterilized to prevent any bacterial growth. Boil the jars and lids for about 10 minutes and let them air dry.
3. Fill and Cover with Oil: Place the garlic in the jar and completely cover it with oil, such as olive oil. The oil helps to keep the garlic submerged and blocks oxygen, which prevents spoilage.
4. Refrigerate: Store the jar in the refrigerator. The cool temperature combined with the anaerobic (oxygen-free) environment created by the oil helps preserve the garlic.

Safety Tips

• Botulism Concern: Garlic is a low-acid vegetable and, when submerged in an anaerobic (oxygen-free) environment like oil, it can become a breeding ground for the bacteria that cause botulism, a rare but potentially deadly illness. To prevent this:
  • Always refrigerate the garlic in oil.
  • Use it within a reasonable time frame—up to three months is safest, though some sources may claim up to six months.
  • Consider adding an acidifying agent like vinegar to the mixture to lower the pH, which helps inhibit bacterial growth.
• Use Acidified Garlic for Longer Storage: If you want to store garlic for a longer period, consider pickling it with vinegar before submerging it in oil. This step adds extra safety by acidifying the garlic.

This method not only preserves garlic but also infuses the oil with a delicious garlic flavor, making it a fantastic addition to dressings, marinades, and cooking. Always ensure food safety by following proper preservation techniques and consult reliable sources or professionals when trying new methods.
