For the filling, chop 5 cherries very finely. Knead with candied peel, candied orange peel and marzipan. Form into a roll (4-5 cm Ø; approx. 45 cm long) to a small thickness.
Roll out half of the puff pastry and cut off crosswise (use the rest of the pastry sheet for other purposes, e.g. freezing). Cut the unrolled pastry sheet in half lengthwise to create 2 strips (approx. 10.5 x 24 cm).
Fold the two strips of dough on each short side into one long strip. Place the marzipan roll on top so that approx. 3 cm remains free on one short side. Then roll up a little and brush the free long edge of the dough with water, roll up further and stick.
Preheat oven (electric cooker: 200°C/circulating air: 180°C/gas: level 4). Line a baking tray with baking paper. Place the roll to the wreath. Place the wreath on the baking tray with the dough seam facing down. Bake in the oven for 25-30 minutes.
Let it cool down.
Halve the almonds lengthwise. Halve 3 cherries. Warm the jam and spread it on the wreath. Decorate immediately with almonds, cherries and candied fruit.
