6.
The jam bars will keep, well wrapped, at room temperature for up to 4 days.

Jam Bars with Chopped Nuts: If you're after textural contrast, chopped nuts added to the top layer give these jam bars extra crunch. After separating the dough, set aside the slightly larger portion to be used for the bottom. Add 1/2 cup/40g sliced almonds or 1/2 cup/50g chopped walnuts to the other third, which will be used for the crumble on top.
