Preheat oven to 475°F and pour 1 tablespoon of oil in 6 cups of a 12-cup muffin tin. Place the muffin tin into the oven once it has preheated. Heat the oil until piping hot, about 2 minutes.
In a large bowl whisk eggs, water, milk, flour, salt and pepper. Whisk until no lumps remain.
Take the muffin tin out of the oven and immediately pour the batter into each of the prepared muffin cups. The batter will sizzle as it starts cooking in the oil. Place the muffin tin back into the oven and bake the puddings until they have puffed up and are golden brown; about 20-25 minutes.
Notes
You can use meat drippings instead of vegetable oil.
Make sure you whisk the ingredients together until there are no lumps.
Be very careful taking the pan with the hot oil out of the oven. It will be piping hot!
Pour the batter ingredients from a bowl into a measuring cup so it is easier to pour the batter into the muffin cups.
Use a spoon to catch the drips from the measuring cup after pouring the batter into each muffin cup. That will help with cleanup!
