Whisk together eggs, then whisk in the milk, water, flour and a pinch of salt. There may be some small lumps, this is fine. Refrigerate overnight or for at least 2 hours to let the mixture rest.
Remove from the fridge one hour before making the puddings to allow the batter to come to room temperature.
Meanwhile, heat the oven to 425F.
Preheat oven to 375F.
Pour 1 tsp of oil in the bottom of each muffin cup. Place the muffin tin on a rack and into the preheated oven. Bake until the oil is steaming hot, approximately 5-10 minutes.
Remove and quickly pour the batter evenly between all the muffins cups. It should sizzle as it is added.
Place back in the oven and bake for approximately 20 minutes, checking often. The puddings will rise and turn golden, dark brown on top.
Remove and serve.
