Ingredients

1 cup unsalted butter, cubed

Preparation

In a small heavy saucepan, melt butter over low heat. Simmer until solids separate from fat, about 10 minutes, but do not allow butter to brown. Remove from heat; skim and discard surface foam.

Slowly pour clear yellow liquid through a fine-mesh strainer into a bowl. Store in an airtight container in the refrigerator for up to 3 months or in the freezer for up to 6 months.
