This is a short newsletter with some tips and recipes for using soybeans in everyday cooking. It was published by Univ of Illinois in 1914.
The document proposes soybeans as a great substitute protein during a time of rationing of meat (I didn't know meat was rationed in the US during WWI).
The USA grows a LOT of soybeans (rivaling corn in both annual acreage and sales). Like corn, the majority of harvested soybean is not used for human consumption. Unlike corn, soybeans are rarely used nowadays as a cooking ingredient in the US. This publication was perhaps an attempt to boost the Illinois economy by promoting a market for soybeans.
Forget the recipes in here. I recommend you show your appreciation for the noble soybean with a tasty snack of edamame. Find a recipe online or visit a Japanese restaurant!
The setting is more static and a bit more introspective than Three Men in a Boat, but I found it just as enjoyable.
I imagine this would have been much more exciting and interesting in its own time, when the audience hadn't already been inundated by submarine movies. The book's anecdotes are now probably familiar archetypical scenes to the average reader.
However, it is noteworthy since it was written by an actual U-202 captain. Unfortunately, it lacks specifics so it doesn't illuminate any historical events (that I know of). Indeed, the author mentions near the beginning that some of the events didn't happen to him personally, but to other captains in his circle of acquaintance.
But it's a quick read and gives some insight into the personality, motives, and demeanor of a WWI U-boat captain.
As the blurb says, the setting is genuinely unique. Combined with the compelling protagonist, the story is clever, well-crafted, and fast-paced. I'm going to seek out more from this author.
