@rootschange try to use some starch instead of flour. If you make the dumplings from uncooked potatos or one half cooked, one half grated raw, try to use the starch from the grated potatos (let the grated potatos sit in water, use a cheese cloth to press the water out, let the water sit until the starch is on the ground of the bowl, remove the water & then you can use it)

But if you just cook all, use store bought starch instead of flour & maybe a little vegan skyr or melted vegan butter :)
