1lb farmer's cheese (tvorog)
2 eggs
6 tbsp sugar
4 oz (1 stick) butter
1.5-2 cups flour, depending on moisture / water content in tvorog?

Melt butter and mix with flour.  Add sugar, eggs, tvorog.
Mix to achieve dough consistency.  Roll into long sausages
on a flour-covered surface; chilling dough in fridge helps
alleviate dough stickiness.  Drop into salted boiling water
for 2-3 minutes, at which point vareniki should rise to the
surface.
