Food Supplies and Planning
Food for the u-boat crew was a bit of a trick. There wasn’t much room for storage and there was no refrigeration.

Recipes
German u-boat recipes are hard to find.
However, The Cook Book of the United States Navy is available on line. This cookbook was revised in 1945, but contains many of the recipes that were used during World War II. http://www.hnsa.org/resources/manuals-documents/single-topic/the-cookbook-of-the-united-states-navy/
