To brown the butter: In a small, deep pot over medium-high heat, cook the butter, whisking frequently to scrape the bottom of the pot, until it’s a light honey color and little brown bits form on the bottom of the pot, 4 to 6 minutes. Remove the pot from the heat and allow the butter to cool slightly for 5 minutes. You should have a scant 1/2 cup (85g) of brown butter.
