(Uborkasalata)
With little or no refrigeration and often only impure water available until the twentieth century, ordinary people did not risk eating fresh vegetables that couldn't be peeled or shelled. Cucumber, beet, or cabbage salads were about the only ones used in Eastern Europe, and cooked salads featuring eggplant or broiled peppers were served in many Mediterranean countries. Lettuce, the base of most crisp salads we eat today, had to be cleaned in sterilized water and eaten immediately.
