Mix all ingrediences (besides the plums…) and let it grow for about 30-40 minutes in a warm place, covered by a wet towel. Probably it won’t grow really high, but that is normal.
Half the plums, take the stone away and wash them
Roll the dough onto a baking tray, and place the plums over it. Place them somewhat standing and overlapping.
Put it into the Oven in around 200 (C) degrees for 25-35 minutes, until the plums are getting soft and brown.
Take it out and sprinkle sugar over it. Depending on the sweetness of the plums, you need different amounts…
