Rinse 10-12 plums in the strainer.
Slice them open, half-way, down the middle and remove the pit.
Fill the cavity with a spoonful of sugar and set aside.
Mix the instant potatoes, cold water and salt.
Once that sets up, mix in the egg.
Then, add the cup of flour.
Use your hands to roll out the dough into a long, snake-like rope.
Slice/section the dough into 10-12 pieces.
Flatten each piece into a circle.
Place the plum in the center and seal by pinching it closed.
Then, gently roll them into a ball.
Carefully drop them into boiling water for about 8 minutes (or until they float).
Remove with a large strainer spoon.
Serve with sides of melted butter, sugar/cinnamon and ground poppyseeds (I'll attach a picture of what the poppyseed grinder looks like.)
