Who wants to warm up with punch when you can have ice cream by the Christmas tree? Vánoční zmrzka is a dessert sour with plums, ginger, gingerbread spices and vanilla, combining intense fruitiness, pleasant acidity and a sweeter, creamy body into one festive creation. For our ice cream pastry sours, we use a vegan ice cream powder instead of lactose. It works in a similar way, helping to create a fuller, smoother and more dessert-like mouthfeel while containing no animal-derived ingredients. Plums bring a deep fruity flavour with a slightly jammy character, ginger adds a fresh spicy kick, and the gingerbread spice blend brings familiar Christmas notes of cinnamon, cloves and other sweet spices. Vanilla then softens the whole profile and ties everything together into one creamy whole. The result is a sweet-and-sour, fruity and spicy pastry sour that tastes a little like plum dessert, a little like gingerbread and a little like ice cream, exactly the kind of subtly over-the-top treat that Christmas calls for.
