Agreeing with the others: it's probably your expectation about the first 
condition which is wrong.

Btw, here's another way to do it

@id = case when @recipes.length == i + 1: 0; when i.remainder(2) == 1: 
1; else 2 end

Although I admit that I'd rather have it on several lines

@id = case
   when @recipes.length == i + 1: 0
   when i.remainder(2) == 1: 1
   else 2
end

Kind regards
