Wash lemons thoroughly under hot water. Then rub the peel finely on a grater (do not rub off the white!) And squeeze out the juice.
Mix the quark with the double cream. Mix in lemon zest and juice, sugar and vanilla sugar well until everything becomes a homogeneous mixture.
Distribute on dessert bowls and decorate nicely with mint and possibly raspberries.
Variation: Put the raspberries (also deep-frozen goods well suited - then let the dessert stand in the refrigerator for a while until the berries have thawed) in bowls and pour the lemon cream on top.
