Step 1
Brown the butter. Might need more than what the recipe calls for to end up with the same amount of liquid? Place butter in pot over medium heat, stir entire time. Butter will begin to sizzle, keep stirring. ~8min, butter will be turning color, and smell buttery/nutty. Pour butter IMMEDIATELY into new, cool bowl. Do not leave in hot pan. Can be done ahead of time. Will resolidify. Can keep in fridge 5 days.
