Chocolate and passion fruit
The most acidic fruit in ordinary pâtisserie use and the pastry chef's favourite chocolate partner. Its acidity is high enough to cut milk and white chocolate, which almost no other fruit manages.
Passion fruit is extremely acidic — considerably more so than citrus in most measures — and its aroma is intensely tropical, sulphurous in the way that reads as exotic rather than unpleasant, and unmistakable at very low concentrations.
That combination makes it the outstanding partner for the chocolates that are hardest to pair. White chocolate has no acidity and no bitterness and is structurally flat; passion fruit supplies both the acid and the aromatic interest in one ingredient, which is why passion fruit and white chocolate ganache is a modern pâtisserie standard rather than a novelty.
With dark chocolate it works differently: the acidity cuts the fat and lifts the whole thing, but the two are competing for attention rather than combining.
The principle
Acidity as a structural ingredient. Use it where the chocolate has none of its own, which means milk, white and ruby before dark.
Pairings
The definitive rescue of white chocolate. The fruit supplies acidity, aroma and colour to a chocolate that has none of the three.
For example: passion fruit and white chocolate ganache; passion fruit bonbons
Enough acidity to cut milk chocolate's sweetness without any competing bitterness to manage.
For example: passion fruit caramel in milk chocolate
Both components are assertive and the result is bright and intense. Some tasters find it exhilarating and some find it a fight.
For example: passion fruit ganache in a 70% shell
Acidity plus bitterness with nothing mediating is a sharp combination. A little cream or a lower percentage smooths it considerably.
Serving
Passion fruit's acidity is high enough to affect a ganache's set. A high-acid purée thins an emulsion, so ganache recipes using it generally carry more chocolate or added butter to compensate.
