I checked this book out from the library in 1st grade (2006-2007), and it involved the story of a poor mother with many children who couldn’t afford to feed her family. She got a job as a maid at a rich woman’s house, and rather than wash her hands after making dough, she would simply take the dough that was on her hands home and make doughs soup. Eventually she meets these people in a forest or something who give her a pot of gold, and give the mean lady she worked for a pot of snakes.

That’s all I can remember, but I would really appreciate the help.
