I do use the favorites mostly for things I want to try. Unfortunately, there’s so many I want to try (relatively speaking of course) that I don’t think I’d notice if a few were missing unless I could distinctly remember what it was. Lately, that’s not likely to happen. LoL.
I screenshot if its something really enticing, then favorite for review later or dang, I need that one ingredient, but i’d buy that one ingredient just for that one recipe.
If its a ADV candidate, I rate and leave a big hi 5 star with kudos, adapt the recipe to 0/1mg nic, print and save to computer for permanent storage. If its not, I rate and go about my day.
