Dissolve the yeast in the warm water. In a large bowl, combine the cottage cheese, sugar, butter, onion, dill seed, salt, soda, and the egg. Add to the yeast mixture, and gradually add enough flour to make a stiff dough, beating well after each addition. Place dough in a greased bowl to rise, and cover it with a light towel. When the dough has doubled in bulk, punch down, turn into a well-buttered round 2-quart casserole or a conventional bread pan and let rise again until light. Bake the bread in a moderate oven (375 degrees F) for 40-50 minutes. Brush the surface with butter.

Poppy seed, caraway, or sesame seed may be substituted for the dill seed or used with it.
