Except babushka didn't have a dumpling shop because private enterprise was outlawed. You probably mean the Pastry Workers' Cooperative, an organization that didn't actually make dumplings because flour and vegetable oil was ratoinalized. The state was exporting those ingredients to the West at a loss in order to obtain dollars and pay back the IMF loans. Instead, the PWC shop had lots of vinegar and pickled cucumbers for sale. Which was too bad, because nobody wanted to buy those things.
