That looks really good. Appreciate the variations as well.
I’ll take a guess and say that the whites folded in make the cake part light and the egg yolks being heavy cause the lemon to sink, and that this is how the layers develop.
Now, the corning ware. I have a 3 piece set. Probably the typical set. I think the largest and the mid sized ones probably hold the same, its just that one is deeper, and the other is larger but more shallow. How deep is the one you use?
It is 3 inches deep - I would have guessed more, but actually measured & that’s what it comes out to.
