I did a search and couldn't find this recipe so I'm posting. Here's what KAF has to say about them. "With only five ingredients, this recipe means you can have popovers mixed up and ready to go into the oven as soon as it's heated up. Half an hour later — hot popovers! The sourdough starter gives them just the slightest tang. And, while these aren't the lightest popovers you'll ever experience, their combination of crisp crust and soft interior is a wonderfully comforting treat." Made these using the muffin pan process as don't have my popover pan here in Trinidad and a fed starter, not as pretty - but did pop up so nice and the texture was lovely with just a hint of sourdough. If you try them hope you enjoy as much as we did.
