Drain the cherries well on a sieve and collect the juice. Mix the marzipan and 5 tablespoons of juice with the whisks of the hand mixer to a creamy mixture. Place one cherry in each star half bowl and press down gently. (Use the rest of the cherries and juice for other purposes). Pour the marzipan mixture into a piping bag with perforated spout and squirt into the stars. Smooth the surface of the stars with a knife. Melt the couverture on a hot water bath, spread over the filled stars with a baking pallet (close the stars).
Allow the chocolate coating to draw a little. In the meantime cut the cherries in half with a sharp knife. Halve the pistachios as well. Press the stars carefully out of the plastic pallet and decorate with the cherries and pistachios. Place in paper praline cuffs as desired and serve
