Finely grind the candied pineapple and lilac one after the other in the universal chopper. Coarsely chop the dark and milk chocolate coating and melt in a warm water bath. Heat the cream, but do not boil.
Take the pot from the stove, melt coconut oil and butter while stirring. Let it cool down a bit. Stir the dissolved chocolate glaze into the lukewarm mixture and mix to a homogenous cream. Quarter the cream.
Mix 1/4 with rum and ground almonds, 1/4 with candied pineapple and 1/4 with espresso powder and coffee liqueur. Stir the orange peel into the last quarter. Line 4 moulds (approx. 15 x 15 cm) with cling film and pour each cream into 1 mould.
Leave to cool, cover with cling film and chill overnight. Turn the truffle masses onto a board and cut them into cubes of approx. 2x2 cm. Line a tray with baking paper. Quickly form truffle cubes into balls with cool hands and lay them on the baking paper.
Prepare 1 small bowl each with ground pistachios, chocolate sprinkles, grated coconut and ground candied lilac flowers. Line a second tray with baking paper. Roll balls in the prepared ingredients with the help of the praline cutlery (spiral fork) (rum pralines in pistachios, pineapple pralines in grated coconut, espresso pralines in chocolate crumbles and orange pralines in candied lilac).
Chill the truffles. Sprinkle with 3 tablespoons of sugar.
