Rationing happened worldwide. That's why it's so interesting to be in the group and see all the different lifestyles and mindsets to make due with what folks had back then. You do what you want to and enjoy the experiment.
Well done! I *think* sausages were not rationed, unless they were canned. Sausages were often made from the odd bits of a meat carcass and perhaps some offal (offal was not rationed). I heard that during more lean years, the sausages might not contain much meat because they had fillers (probably oats and maybe some root vegetables). Do not worry about making it "authentic." Your family has been doing so well with these challenges! I love seeing your videos! 👍
