According to Rach, you should always make extra gravy on Turkey Day no matter what! But, we're all human, and it's possible you did run out (tsk, tsk), here's how to make more in a pinch. Take equal amounts of flour and butter -- melt butter until it bubbles and starts to turn golden. Whisk in the flour, course black pepper and some stock. In minutes, you have gravy! For a deeper color and added flavor, add in a little Worcestershire sauce and you're done!
