Bake for about 30 minutes, watching the pastry for colour towards the end of cooking.
Remarks
A common mistake with Linzer torte these days is to make it too sweet. This is why it is important to use this special pastry, rather than classic sweetcrust pastry, and also why adding the stewed apple is a good tip.
Ground hazelnuts can be used instead of almonds.
You can brush the lattice strips with beaten egg-yolk to glaze them and help them brown more quickly.
