Generally speaking, recipes can’t be copyrighted (the specific wording of a written recipe might be protected, but the general idea of combining certain ingredients in a specific way can’t)
The names of the flavors, branding, etc. can be (or trademarked, or various other IP terms)
And aspects of the production process might be covered by patents and such.
And of course non-competes and such could complicate things for the actual people involved
And how you acquire those recipes can be a factor, that could rub up against non-disclosure agreements, corporate espionage laws, etc. you may need to be able to say that you came up with it on your own independent of the original recipe or pieced it together from publicly available information.
But in general, if anyone wanted to start up an ice cream company selling exact duplicates of Ben & Jerry’s flavors,they could do that as long as they called them all something different
I think I see a bit of steam escaping from the pan, so I think they tried to weigh it after cooking
Which makes sense, there’s going to be some weight change after you cook it because of evaporation and such… hence the steam
Before cooking you couldn’t really call it Jollof Rice, it would just be a big pot of the raw ingredients for Jollof Rice
And they know the weight of the ingredients going in already, they’re quoted in the article, so that’s just simple addition to figure out.
