Hi THINKVATO, The thing u have to remember about any pastry flavoring with fruit or the likes, is infuse, infuse, infuse. Then incorporate the infused (ex) milk into (ex) chocolate, custard, dough, and the list goes on. Soooo, find a recipe and substitute the passion fruit for other flavorings, BUT remember you need to take out some of the liquid. It really is a thought process---not too difficult. OK?
