Another example would be a glazed donut (starch surrounded by sugar).

But what if it is a donut that is both filled and glazed? Is the glaze just on top or all the way round?

What does a beef Wellington count as? It has multiple nested layers... what if you made a turducken and wrapped each bird in a flatbread of some kind, before stuffing it in a larger bird?

Beef Wellington is in the same class as calzones. Possibly as a cascade thereof.

Doesn't the toroidal topology of a donut mean that both the starch and sugar are simultaneously surrounding each other?
