Step 1

Add 1/4 teaspoon vegetable oil to 10 muffin cups (leave the middle two empty). Turn oven on to 400° and place muffin tin in oven to heat while you make the batter.

Step 2

In a medium bowl, whisk eggs and milk together. Add flour and salt; whisk until smooth. Whisk in melted butter.

Step 3

Pour batter into a measuring cup for easy pouring. Remove now-hot tin from the oven and pour batter evenly into the ten oiled cups.

Step 4

Bake popovers for 30-40 minutes, at which point they should be puffed and crispy. Serve immediately.
