The way ingredients and other things are described. I felt that explaining that a single word ingredient, requires @ only, but if you use multiple words, you have to use @ingredient with space{}, with the empty `{}` at the end can be too complicated to explain.

I felt that for someone who is not familiar with these things, it can be confusing. In recipe-lang the explanation is IMO simpler: wrap the ingredient with `{}`, there are no ambiguities. {salt} or {ingredient with space}, it's quite clear where the ingredient starts and end.

Once they learn that, everything else is a prefix of the curly braces, timer? t{}, link to another recipe? @{}, material? &{}. I'm considering for images something like i{} but I haven't had time to experiment with it.
