The Yorkshire pudding that you cooked looks like a large yeast roll or biscuit (not a "cookie" type, but a breakfast type biscuit that we eat here...like these that I made for Thanksgiving morning....
We eat those with syrup (I like maple syrup), gravy, fruit jellies or honey.
Your biscuits are similar to our sconces Yorkshire pudding is a batter pudding basically a pancake mix but your pancake mix is made with baking powder ours is not.
