If you want to get started on trail cooking, turn to page 318 of The Boy Scout Handbook (14th edition, page 336 in the 13th edition). Choose one ingredient from each column, scale the amounts, and you are on your way.
Since the 11th edition Scout handbook in 1998, the cooking chapter has included a great “choose your own stew” recipe. It might have been in the 10th edition, but I don’t have one of those handy.
The 11th and 12th edition have slightly different lists, so I’ve combined both to make one table. I’ve also split vegetables out into their own column, since they are not really the same thing as cheese or nuts.
