Cut potatoes into small pieces, put in a pot with cold water and bring to a boil.
Lower the temperature and cook until potato becomes very soft (for 20-30 minutes).
When it is cooked, take it out of the water and mash.
Wait for it to cool down a bit, then add maple syrup and yoghurt and mix it all together.
Gradually add flour and corn starch and mix it in. Knead it until you get a soft dough. If it is still a bit sticky, add some more flour.
Seperate the dough into 4 equal pieces.
Form each piece into a circle, put strawberry in the middle (you can add a small teaspoon of sugar if you prefer it sweeter) and carefully close it and form into a ball. Put it on a plate covered with flour.
Cover dumplings with foil and put in the fridge for around one hour.
Then put water in a wide pot and bring to a boil.
When it's boiling put dumplings in water, lower the temperature and cook for 15 minutes (make sure it's boiling all the time).
Meanwhile prepare walnuts or bread crumbs, whichever you like better. We use walnut meal and put it in a hot pan for one minute, so it gets a very good flavour.
When dumplings are cooked, put them on a plate, sprinkle with walnuts and cinnamon. If you like, you can also sprinkle some vanilla flavoured sugar for a perfect taste.
You can also prepare some cooked strawberries on the side to dip dumplings in them.
