Wash, dry, and pit the fruit and cut it into small pieces if necessary. In a bowl, mix the vegan whipped cream with the quark cream. You can also use vegan quark. Cover the bottom of a sealable glass dish with the cream. Add the seeds, mango slices, and a few chopped orange slices to taste. Place the ladyfingers (sugared side down) on top of the seeds and mango, packing them tightly together, and press down. Drizzle over some freshly squeezed orange juice and pomegranate juice. Again, cover well with the mixture of vanilla quark and vegan whipped cream, add another layer of fruit, press down another layer of ladyfingers, drizzle with juice, and sprinkle with more seeds if you like. Cover with the rest of the cream. Seal and leave in the fridge for at least 24 hours (preferably 48 hours).
