Cook the meat in a little water until soft, cut it into small pieces and puree it. Wash the parsnips well, cut them into small pieces and sauté them together with the peeled and chopped potatoes in a little water or the meat broth (those from cooking, without salt) until soft. Now add the pureed meat and let it boil once. Then, if desired, pour in the fruit juice and puree everything again. Finally, stir in the rapeseed oil.
If you choose fruit puree, it is easiest to feed it as dessert.
