Browning butter is such a simple technique that brings amazing flavor. It’s simply butter that has melted, and then cooked a step further so that the milk solids in the butter caramelize. Adding extra milk powder makes it even better!
Let the butter melt in a medium saucepan over medium heat. Use a light-colored pan, or you will struggle to see the caramelization of the milk solids and might burn them.
Once the butter melts, let it cook for around 3-4 minutes, regularly whisking.
Once it starts to foam, add milk powder if using, and whisk until it browns into a deep amber color and smells nutty and caramel-like.
Pour the melted butter, including all the caramelized bits, from the bottom of the pan into a heat-proof bowl.
Notes
The milk powder is optional but adds a lot of extra flavor. If you omit it, follow the recipe the same, just leave out the milk powder.
