When I was very young (and don't ask!), my parents used to buy a lemon chiffon cake that came in a loaf shape and had chocolate frosting.
We lived near a Hanscom's and a Horn and Hardart Retail Shop, and sometimes shopped at Broad and Olney, though I don't remember a bakery there. We also were not far from Peter Pan and Bogoslafsky's, but it wasn't their style.
Does anyone remember that cake? Who sold it?
I know that I could figure out how to bake it, but I would love to know where we used to buy it.
One more puzzle to torture the brain!
