Beat the eggs and sugar with the whisk of the hand mixer until the mixture is light. Mix in the lemon zest and ginger. Likewise, carefully fold in the whipped cream and fill it into a mold with a capacity of approx. 1 liter. Cover and freeze for 4-5 hours.
For the compote, cook all the ingredients for about 5 minutes until they are just soft and allow to cool. Remove the parfait from the mold, cut into slices and serve with the rhubarb compote.
