Garlic Infused Olive Oil

Ask the Test Kitchen

Because garlic is low in acid, it can promote the growth of bacteria that causes botulism—a definite health hazard to humans. Rather than make your own, we recommend that you use only commercially prepared infused oils…and store them according to the manufacturer’s instructions on the label.
