It’s all becoming clear to me now…
The main reason most Linzer tortes are made with short crust these days — or so I’ve come to believe — has to do with a certain technical issue. Reader Gerhard has convinced me that originally Linzer tortes were indeed cake-like and not tart-like, with red currant (or black currant) jam on the top.
But here’s the sticky detail: jam is gooey. It soaks into cake when you bake it on top of a liquid (or semi-liquid) batter. So how did the originators of the modern Linzer torte achieve a separation of the two? The answer: by applying paper-thin wafers to the batter and then spreading jam over them. Back-Oblaten they’re called…”baking wafers.” The jam goes on the wafer, the wafer provides a barrier and probably absorbs enough moisture from the jam during baking that you don’t know it’s there afterward.
