What preparation method, famously used by European sailors, helped ward off scurvy?

Answer

Pickled cabbage, or sauerkraut

Pickled cabbage, universally known as sauerkraut, served a vital role in the nutrition of European sailors during extended voyages across the oceans. This preserved form of cabbage provided essential nutrients that were otherwise scarce on long sea journeys, specifically helping to prevent the development of scurvy, a disease caused by severe Vitamin C deficiency. The fermentation process inherent in making sauerkraut allowed for the long-term storage of the vegetable while retaining necessary dietary components.
