3/4 cup all-purpose flour
1/2 teaspoon salt
3 eggs, room temperature
3/4 cup milk, room temperature
1/2 cup pan drippings from roast prime rib of beef (beef juices and oil)*
* If you do not have enough pan drippings, add melted butter.
At least two (2) hours or overnight before you will need this Yorkshire Pudding batter, prepare the batter (minus pan drippings), and place in the refrigerator.
Yorkshire Pudding is cooked after you have taken your cooked prime rib roast out of the oven and you are letting it sit for the required resting period.
In a large bowl, sift together the flour and salt.
In another bowl, beat together the eggs and milk until light and foamy. Stir in the flour/salt mixture just until incorporated and smooth. NOTE: The batter will be like a very thin pancake batter
Cover bowl with plastic wrap and refrigerate at least two (2) hours (for best results, refrigerate overnight).
