Yorkshire Pudding

Yorkshire Pudding
4 eggs
2 cups milk
2 cups flour
Roast Drippings

Mix all ingredients together and put in a bowl to chill in the fridge while your roast is cooking.
After you take out your roast from the oven to rest, this is when you want to cook your yorkshire.

In a 9x13 pan place about 3 tablespoons of roast drippings in the bottom. Take your batter out of the fridge and stir it before pouring it in your pan. Pour mixture in your pan and then bake at 425* for 30 minutes or until it starts to brown on top.
