Cut butter into small pieces and place it in a medium skillet set over medium-high heat.
Allow the butter to cook until it has fully melted, about 2 minutes.
Next, gently swirl the pan for 2-3 minutes or until it begins to smell nutty and turn golden brown. The butter will foam on top, but you’ll be able to see the color underneath as you swirl the pan.
As soon as the butter turns golden brown, remove it from the pan, so it doesn’t burn.
Transfer the butter to a heat-proof container or bowl.
Store the browned butter in an airtight container in the fridge for up to ten days.
