Coarsely chop the chocolate coating and coconut oil and melt over a warm water bath. Leave to cool for about 10 minutes. In the meantime inflate balloons (approx. the size of a grapefruit). Carefully clean the balloons all around with water and rub them dry well. Line a plate with baking paper
Dip the balloons one after the other well up to halfway into the couverture. Lift them out and let them drip off very well. Place them side by side on the baking paper. Allow to dry a little (refrigerate if necessary). Dip the balloons 2-3 more times into the remaining couverture, drain and allow to dry as described. Chill the balloons for about 2 hours
For the cream, mix mascarpone, sour cream, icing sugar and vanillin sugar until creamy. Stir in egg liqueur, up to approx. 50 ml, in streaks. Drain cherries well. Chop the pistachios
Carefully prick the knotted opening of the balloons with a needle and let the air out slowly. Carefully remove the balloons from the chocolate bowls. Layer cream and cherries in the chocolate bowls, sprinkle with pistachios and place on small plates
waiting time approx. 2 1/4 hours
