Unusual use of crackers
The mother of a friend of mine used to make a mock apple pie with Ritz Crackers (British, a small, thin biscuit made with butter, or an imitation, to give it a buttery taste, lightly salted, baked golden brown). I forget what it was made of, the only thing I remember is vinegar, but you soaked the crackers in a liquid, then layered them into a piecrust and topped with a top crust. It tasted very much like apple pie. I have no idea why anyone ever bothered, as it was not cheaper, or less trouble, to make than a real apple pie. I think the only reason anyone made them was to show that it could be done.
