Stir occasionally and allow butter to start to foam.
Keep stirring until little bits of brown start to develop in skillet. Roughly 8 minutes (adjust accordingly)
Stir and remove from heat immediately and pour into heat proof bowl.
Cover and place in refrigerator and allow for butter to turn back into solid state. Roughly 45 minutes to an hour. Just enough to make the butter solidify but still workable.
