To a light-bottomed pan, such as stainless steel, add the stick of butter and turn flame on to a medium heat. The butter will melt down, then begin to sputter.
Using a wooden spoon, consistently stir the butter on a medium heat, ensuring the solids do not burn at the bottom. Let the butter start to brown; keeping an eye on the butter for 2-3 minutes.
When you see the color change to a light or medium amber color, turn off the heat and remove the pan from the stove, then add the sage.
