Preheat oven to 450 degrees F
Mix together flour and salt, creating a well in the center
Add milk and eggs, whisking until just combined - you want the batter to have small lumps (this helps with the pop) And no, larger lumps aren't better
Pour the batter into a pitcher or bowl with a spout- you want to be able to easily pour into the muffin or popover tin
Place 12 cup muffin (or popover) tin into the oven for 3 minutes to warm
Remove from oven, and spoon 1 teaspoon of melted butter into each cup (you do not need to use a liner)
Divide the batter evenly, filling about half-full
Bake for 10 minutes at 450 degrees F, then reduce to 375 degrees F and continue to bake for 20-25 minutes
REPEAT AFTER ME, DO NOT OPEN THE OVEN AT ANY POINT
Once your timer digs, remove from the oven, and using your fingers, carefully remove the popovers
Best served warm with butter, jam or a good sprinkle of cinnamon sugar. You can also serve with savory meals- dipping in gravy, or as a dinner roll
