Traditionally, Yorkshire pudding was served with roast beef in the county of Yorkshire, England. The batter was placed under the meat to catch the meat drippings, but if you do not have any drippings just use a little oil at the bottom of your tins. Whisk together 4 eggs, 200ml milk, 100g cake flour, and salt and pepper to taste. Rest for 1 hour. Preheat the oven to 220°C. Use shallow muffin tins or 1 large baking tray and pour the milk mixture into the prepared tins. Bake until puffy, crispy and brown. Also delicious served with sugar and cinnamon.
