Meanwhile, brown the butter. Place 3/4 cup unsalted butter in a medium, light-colored heavy-bottomed pan over medium heat. Whisk gently, as it continues to melt — the butter will become foamy and bubbly. After about 4 to 5 minutes, you should see brown bits start to appear at the bottom of the pan. The butter should be a golden color and emit a delicious, nutty aroma. Remove from heat immediately, and whisk for another 30 seconds before setting on a wire rack to cool.
