Not sure if this is a bug, but when cooking most recipes, when it asks you for a "cooking pot" you can actually use any container (tub, bowl, bag). This may be helpful at the beginning if you're living off porridge (no idea why you would that, since eating 1 pound of flour will completely fill you), since for some weird reason you can only make about 1 pound of porridge at a time, even tho pots have a capacity of 6 lbs.
This is probably not a good idea when making soup since soup recipes require almost exactly 6 lbs, so using bowls probably would waste a lot. But tubs, bags, etc are ok if you run out of pots like me. (I often buy barley/rye grains that I can turn into flour and get to kep the bag... a bag holds 12 pounds).
EDIT: also, the "raws" now have different kinds of nutrition values, but I have no idea if these have any long-term effect or are simply different values that add to the total "nutrition". The way I'd program food into a game, I'd make different vitamins, proteins, etc have an effect over the long term (like, not eating any protein for a month), but only caloric intake would matter for the day-to-day.
EDIT2: also, btw, fish soup is GREAT. make sure you get lots of leaves for seasoning in the months after summer, and tons of turnips, you can turn 2 pounds of fish into a whoopin' 6 pounds of delicious nutricious scrumptious soup.
