There are many different methods for making basil infused oil, but I find this one works really well. It produces a deeply colored and flavored oil that will last in the refrigerator for 3-5 days before the flavor begins to drop off. It can be frozen for a month or two without much loss of flavor, but be sure to wrap it closely once frozen. Use this as a garnish, or as a flavoring. Try smearing a little across a plate when you want a subtle basil aroma and flavor, or add drops onto dishes for small intense burst of basil flavor. Although the recipe calls for olive oil, save the intense Tuscan Extra Virgin oils for something else, or the basil will be overwhelmed.
