Buttery Popovers

Heat oven to 425 degrees. Whisk together the milk, flour, and salt until just incorporated. The mixture will be lumpy.

Beat in eggs and egg yolks, one at a time, until just incorporated. Be careful not to overmix. The batter should still be lumpy.

Brush inside of popover tins with a generous amount of butter. Divide batter evenly among buttered tins. Bake 20 minutes.

Reduce oven temperature to 350 degrees; bake until puffed and golden brown, 15 to 20 minutes more. Remove tins from oven, and turn out popovers; serve immediately.
