Ask anyone who has had a popover before and the chances are that they’ll describe them as almost magical. First, there’s the way the batter puffs up, creating a hollow space inside the roll. Then, there’s the sound it makes when you break into it like an eggshell. And finally, there’s the taste itself: slightly sweet and salty, buttery, and above all else light as air.It’s no wonder people who have had them want to try making them at home. But while they may be delicious on their own, most recipes include serving a side dish alongside these savory rolls to make a full meal.The reason? Popovers aren’t very filling by themselves. Like a soufflé or a waffle cone, they’re mostly made of air, so you have to pair them with something else if you hope to stave off hunger for more than an hour or two.
