Preheat oven to 450 degrees F (230 degrees C).
Take a 12-hole muffin tin, and drop a teaspoon of oil in each of the holes. Place the muffin tin into the hot oven for 5-10 minutes, or until the oil starts to smoke.
Meanwhile, stir the flour, milk, salt, and eggs together. Take the muffin tin out of the oven, and pour batter into each of the holes. Bake for about 15-18 minutes or until the edges are a deep golden brown. Resist the urge to open door before the puddings are ready because they could deflate!! Just check them by turning on your oven light.
Serve with gravy (or whatever else you prefer) immediately.
