For the blueberry pot dessert with brittle, heat 80 g sugar in a dry frying pan until it melts and turns light brown. Add almond slivers and stir to coat with the caramel.
Spread the brittle mixture on a baking sheet brushed with oil. Let cool and then chop into small pieces.
Mix curd with lemon zest, yogurt, vanilla sugar and juice. Whip the cream until stiff and gently fold in.
Wash the blueberries, sort them out, drain well and mix with the remaining sugar.
Arrange the blueberry pot dessert sprinkled with brittle, garnish with blueberries and serve.
