Quickly knead the flour, butter, sugar, egg and salt into a shortcrust pastry, leave to rest in a cool place.
For the filling, mix the jams with the ground nuts to a pulpy mass.
Do not roll out the shortcrust pastry too thinly, spread the jam mixture thinly and roll it up tightly, wrap in cling film and put in the freezer for 20 minutes (this makes it easier to cut).
Cut off 5 mm slices, place on the baking sheet and bake at 160 ° (hot air) or 180 ° in a preheated oven until they are lightly colored.
You can also use other jams and nuts or coconut flakes.
