Cut potatoes into small pieces, put in a pot with cold water and bring to a boil.

Lower the temperature and cook them 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 agave syrup, oat flour, semolina and corn starch and knead it until you get a soft dough. If it is still a bit sticky, add some more oat flour.

Separate the dough into 6 equal pieces.

Form each piece into a circle, put half of plum 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.

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).

You can also prepare some cooked plums on the side to dip dumplings in them.
