• 2 tbsp butter (or fat)
• 2 tbsp flour
• 1 1/4 cup liquid (drippings, broth, or combination thereof)

On medium heat, melt butter, then whisk flour in and heat for ~2min (not hot enough for it to burn, but after a couple of minutes, it should start to turn to light brown).

Add in the liquid, keep stirring, about ~3min, it will thicken pretty quickly…
