I think it’d be cool if there was a way to see recipes that have been adapted from the recipe you’re viewing. Maybe a list at the bottom of the recipe’s page of any recipe that is public that has been made as an adaptation. I thought that might solve a couple of problems…1) Easily see adaptations on your own recipes and changes others have made. It might help you tweak your own recipe or come up with something you hadn’t thought of. Although that might cause problems if people get pissy about others using their recipes. 2) See adaptations other people have made of recipes you would like to try. One of the adaptations might have all the flavors you have or clues on what to sub. 3) Might help people be more responsible with the adaptation system if they know it will be seen as an adaptation.
Just thoughts I had last night when sifting through adaptations I’d made to others’ recipes.
