For a perfect accompaniment for a savory roast beef I tried to make the yorkshire pudding recipe using the drippings influenced by the julia child recipes, I have tried all the tricks of trade but have failed each time. This time I want to seek your help to perfect my yorkshire pudding recipe. How do I make a perfect recipe using the drippings? I have 3 eggs, 1 cup of whole milk, 1/2 tsp of salt, 1 cup plain flour and about 3 tbsp of reserved beef drippings. How do I proceed from here, from the ingredients part to the preparation and cooking portion?
