Linzer sweets: the window shows the filling

Useful to know

Linzer cookies sandwich a filling between two baked pieces. An opening in the upper piece reveals the filling. King Arthur’s recipe uses a nut ingredient in the dough and a fruit filling. [1]

Cut matching pairs with the same outer dimensions rather than shaping every piece randomly. The opening is decorative but still needs a sufficiently strong surrounding cookie. The recipe includes chilling the cut pieces to help preserve their shape. That rest is part of the method rather than an unnecessary delay.
