How to Brown Butter

Have you ever browned butter? It's an easy way to take a recipe that relies on butter up a notch in flavor. Just by cooking the butter a little past the melting point results in the milk solids in the butter browning, and creating a wonderfully nutty aroma. It's fun to do with butter-based sauces, baked goods that call for melted butter, or with vegetables such as winter squash that you sauté in butter. Just be sure to keep your eye on it while cooking; it's pretty easy to go from browned to burnt.
How to make Brown Butter:
INGREDIENTS,
Unsalted butter, sliced into tablespoon sized slices,
METHOD:

1) Heat a thick-bottomed skillet on medium heat. Add the sliced butter (sliced so that the butter melts more evenly) whisking frequently. Continue to cook the butter.

2) Once melted the butter will foam up a bit, then subside. Watch carefully as lightly browned specks begin to form at the bottom of the pan. Smell the butter; it should have a nutty aroma. Remove from heat and place on a cool surface to help stop the butter from cooking further and perhaps burning.

 It's pretty easy to overcook browned butter and go from brown to burnt. If the butter starts to blacken, I suggest dumping it and starting over (something I've had to do on occasion), unless you want beurre noir which has a different taste than nutty brown butter.
If you want to make sage brown butter sauce, add some fresh sage leaves to the butter once it has melted. Allow the butter to brown and remove from heat.
Use browned butter immediately or store covered in the refrigerator for future use.
