We're intrigued. It sounds a cross between a pie and a Pop-Tart.
Imagine the possibilities – this would be a great use for homemade preserves, maybe even something savory like Oven-Roasted Tomato Jam with an herbed crust. Or a gingerbread crust with lemon curd filling.
The toaster idea also has us thinking. How great would it be to freeze a batch of these and pop one into your lunch bag for a treat at the office? It would also be a great homemade after-school snack to keep on hand.
But first, we need to track down a recipe. Anybody have one?
If it's really a retro treat, they must be out there somewhere. Maybe you know the retro bubble by some other name? Let us know!
