Potato dumplings with plums





1 kg potato


2 small cups oil


2 eggs


15-20 Tbs wheat groats


15-20 (or more) flour


salt


bread crumbs (as much as you need) for later usage


some sugar


about 20 medium plums











Cook whole potatoes without peeling. When they are done, let them cool and then peel and mash. Add wheat groats, oil, flour and eggs. Knead well 鈥?it should be hard, not sticky. Fry bread crumbs in a pan (without oil!) until golden and set aside. Mix with sugar.





Boil water in shallow and wide pot. Take little dough and place around plum to make a little ball. Put them in boiling water 鈥?they are done when they start floating. Take them out with latticed spoon and roll them into mixed bread crumbs and sugar.
