Cut the mango into very small cubes. Heat up the jam, pass through a sieve and mix with the mango pieces to a thick smooth mixture
Roll out the dough into a square (approx. 30 x 30 cm) on a floured work surface. Spread the dough evenly with the mango-apricot jam and roll up tightly. Put the dough roll in a cool place for approx. 30 minutes
Cut the roll of dough with a sharp knife into approx. 0.5 cm thick slices. Put the short pastry snails on 2 baking trays lined with baking paper
Bake the trays one after the other in a preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 8-10 minutes
Remove the sheets, cool them down a little. Let snails cool down on a cake rack
