- In a meantime, generously grease (using soft butter) popover tins. If you do not have popover tins, use large muffin tins or custard dishes. Pour 1/4 cup of batter into each tin. There might be a little bit of leftover batter, distribute it evenly among all the tins. Transfer popovers into the hot oven. Bake without opening the oven for 30-35 min. Take the popovers out and enjoy right away.
Two most important elements of this recipe are preheated oven and lukewarm milk. Cold milk will make popovers dense and they will not rise as high. There is also a necessary step at the end, to let the batter rest before baking. It allows the gluten to relax and starch grains to swell resulting in much more light and fluffy popovers.
