Use this herb-infused oil, from chef Frank Stitt's "Bottega Favorita" cookbook, to make his Butter Bean-and-Mint Pilaf.
Prepare and ice-water bath; set aside. Bring 4 cups water and salt to a boil in a medium saucepan. Add mint leaves and cook 10 to 15 seconds. Drain, and immediately transfer to ice-water bath to cool. Drain and squeeze dry.
Place half of the mint leaves in the jar of a blender with enough oil to cover; blend for 2 minutes. Add remaining leaves and oil and blend for 2 minutes more. Transfer to an airtight container and refrigerate overnight.
Strain mint oil through cheesecloth and discard solids. Oil can be kept in an airtight container, refrigerated, for up to 5 days.
