Combine the basil and il in the bowl of a food processor or blender and puree for 10 seconds. Transfer the mixture to a 1/2-pint Mason jar, cover, and set aside for about 1 hour, until the basil settles to the bottom. Strain the contents through a fine sieve into a 1-cup glass measuring cup. The oil should be ready to use immediately. It must be stored in the refrigerator, where it has a shelf life of up to 1 week.
