Place the pieces of butter in your light-coloured pan.
Turn the heat onto medium. Medium heat ensures the butter cooks evenly.
Begin stirring to move the butter around as it melts.
Once melted, the butter will begin to foam and sizzle around the edges.
Keep stirring.
In about 5-8 minutes from when you started (depending on the amount of butter you used), the butter will turn golden brown.
The foam will slightly subside and the milk solids on the bottom of the pan will toast.
Remove immediately from the heat and pour the butter into a heat proof bowl.
It will smell intensely buttery, nutty, and rich.
