Combine flour and salt in a medium sized bowl. Add the eggs and a little of the milk. You can use a whisk or a hand held mixer.
Whisk until smooth, then gradually add the remaining milk.
Measure one teaspoon of oil into each hole of a 6 cup popover pan. Transfer the baking pan to the oven for 5 minutes, or until the pan and oil are hot.
Carefully remove the pan from the oven and pour the batter equally between the cups. Each cup should be slightly less than half full. Return the batter quickly to the oven and cook for 28-30 minutes, or until golden-brown and well-risen. Baking time may be reduced if you’re making 12 popovers in muffin tins. Serve immediately.
