This is the traditional paella recipe. Substitutions won't work well. Make sure to use Spanish chorizo, not Mexican chorizo, which is a whole different thing. Some people substitute tumeric for saffron. It will not have the same taste.
I created this in response to a post looking for a recipe for this dish that was either nutty or with coconut. I also saw some other post that had preferred recipes without tomatoes.
I will be also experimenting with trying this with wine.
