OK. There used to be a place in the heart of O.county, in Lake Forest or some such place near Laguna Niguel called the Swedish Sandwich Cake Shop. They had a great specialty for parties etc., a Sandwich cake. It looked like a cake, with icing and flower decor. and layers, but it was made of savory ingredients, salmon paste, eggs, bread, etc.
You would cut into it like a cake and serve slices, but 'tweren't sweet.
So, the following is listed in the LA times
Original Swedish Sandwich Cake
20651 Lake Forest Dr
Suite A109, Lake Forest
But I don't live nearby and they don't answer the phone. ANyone?
