This recipe originates from the Vaud district of Switzerland, where both the pastry and filling are local specialties.
The pastry relies on baking powder rather than egg or ice-cold butter, giving it a unique crumbly texture. Handle the dough gently to keep it tender.
Use a dry white wine such as Sauvignon Blanc or Pinot Grigio for the best flavor balance against the cinnamon.
The tart is best served slightly warm or at room temperature. The filling will harden as it cools, creating a crisp, glass-like topping.
