Sift the flour and salt into a bowl.  Make a depression in the middle of the flour and pour in the beaten eggs.  Whisk the eggs into the flour mixture until a paste forms.  Gradually whisk in the milk, 1/2 cup at a time.  Cover with plastic and chill in the refrigerator.  Preheat the oven to 425 degrees.  If you are making a meat dish and have the drippings available, use them.  Otherwise, pour the melted butter into a 9" x 13" cake pan (it should be about 1/4 inch deep).  Put the pan containing the drippings or butter into the oven for about 5 minutes so that it is very hot.  Remove the batter from the refrigerator and whisk it well before pouring it into the hot pan (it should be about 5/8 inch deep).  Return the pan to the oven and cook until crisp and golden (about 20 to 30 minutes).

Our comments:  This is a great alternative to potatoes, rice or pasta when you want to serve something different with a meat dish.  We wouldn't make Yorkshire Pudding unless we had some good gravy to serve over it.  It's a natural with Prime Rib, but we haven't mastered Prime Rib yet.  Maybe next year.
