It takes five minutes to make brown butter. You can use it almost anytime a recipe calls for melted butter (hello, brown butter chocolate chip cookies).
1 cup (227g) butter, salted or unsalted
Add butter to a heavy-bottomed pan over medium-low heat. As the butter melts, continuously swirl it around the pan. The butter will quickly go from brown to burnt, so stay close to the pan when you do this.
Continue swirling the butter over the heat. It will melt, get a little foamy, and finally start turning golden brown. Remove it from the heat when the butter is light brown and smells nutty.
Store brown butter in the fridge for up to two weeks or freeze for up to three months.
