Melt butter slowly over medium-low heat in a saucepan. Once melted, increase heat slightly and stir frequently with a wooden spoon. The butter will bubble as water evaporates. Watch closely as milk solids begin to toast and brown bits form at the bottom. Remove from heat immediately when butter has swirls of browned bits. Allow to cool for 10 minutes.
