Beat eggs until foamy, then add remaining ingredients and beat until smooth. Do not overmix.
Refrigerate 1 to 8 hours.
Pour batter into popover cups which have been buttered or sprayed, and place in cold oven. Turn heat to 375, bake 30 minutes without opening oven door. Pierce the side of each one to allow steam to escape before continuing to bake them 10 to 15 minutes longer, until firm and golden.
Let cool briefly, the pierce each one again to release steam. Serve while warm.
Note: if not pierced, they will still be delicious, just a little wetter inside.
