Brown Butter- Cut butter into chunks to help it melt evenly. Cook on medium-low heat and stir frequently. Heat until butter just starts to brown and has a "nutty" smell. There will be some some brown bits on the the bottom. This is good! They have lots of flavor. Stir frequently and don't let it burn! If it turns black, it's burnt and you need to start again. Remove butter from heat and allow to cool. You can add it to the fridge to speed up the process. Once it's starts to solidify, you're good to go!
