Fool-Proof Popovers

I woke up a little after 6 this morning and was watching the Food Network. Melissa D'Arabian has a new show called $10 Dollar Dinners. She made these popovers look so yummy and easy. I have never tried making a popover before so I was ecstatic when they popped and stayed popped! She said the biggest secret is to have room temperature ingredients.

3 tablespoons melted butter, divided
2 eggs
1 cup milk, warmed for 30 seconds in the microwave (should be lukewarm to warm)
1 cup all-purpose flour
1 teaspoon kosher salt

Preheat the oven to 400 degrees F.

Using a pastry brush, coat 8 muffin cups with 1 tablespoon of the melted butter and put the tin in the oven for 5 minutes. Meanwhile, mix the eggs in a blender until light yellow. Add the warmed milk and blend. Add the flour, salt and remaining melted butter, and blend until smooth. Pour the batter into the warmed muffin tin and return it to the oven to bake until golden, about 35 minutes. Remove from the oven and serve warm.
