Pastitsio (Greek Cinnamon Beef Macaroni Bechamel Bake)
Cut a square of pastitsio and three layers should show clearly: macaroni, a cinnamon-scented beef sauce, and a thick cap of bechamel. Each layer has its own way to fail. Macaroni boiled fully soft keeps softening in the oven, and a beef sauce with liquid pooling underneath soaks the pasta below it. The 15-minute rest after baking lets sauce and pasta set, so a knife pressed straight down leaves all three layers clean.
