I need greater looseness for acceptable substitutes when searching for cocktails I can make. For instance, I don't usually buy Cointreau, but I always have Dry Curacao on hand and would like to be able to use that as a substitute for any recipe that calls for Cointreau without having to edit every single recipe and mark that as an acceptable substitute. As best I can tell, the substitutions listed on an ingredient page are ONLY based on whether any recipes specify a substitution, and additionally, substitution suggestions aren't automatic at all.

Describe the solution you'd like
I see a couple potential solutions here:

• Create a substitution list tied to a shelf: this allows a bar or user to control what substitutions they're willing to make without editing recipes, and localizes it to a particular entity.
• Add the ability to allow for "cousins" to be substituted. For example, since Cointreau and Dry Curacao are both variants of Orange Curacao, create a method for allowing those two to be substituted when searching for cocktails "I can make". This would also probably need to traverse the variant tree (so that a variant of Dry Curacao would also be listed as a sub). Figuring out acceptable tree distances would probably be pretty hard, so this is probably not the best way to go.
• Add a method of bulk updating recipes that call for a particular ingredient to allow for a substitution. This is pretty straightforward, but makes it so sharing recipes means accepting the substitutions of the bar/user that shares them, which might not be appropriate.

Additional context
This is one of a few broader substitution features I'd like to see - I can imagine a more complex scenario here where you might want to be able to specify an adjustment when performing a substitution, e.g. if a cocktail calls for Grand Marnier, you can sub with Dry Curacao but you need to adjust your sweetness by increasing another sweet ingredient or by adding simple syrup. Being able to automatically make these changes using the tool would be amazing!

Hello,
not sure if you are using the latest version, but you can create a hierarchy of ingredients. So in your case, you can create an hierarchy like this:

┌──────────┐                        
│ Liqueurs │                        
└────┬─────┘                        
     │  ┌───────────────┐           
     └──┤Orange curacao │           
        └───────┬───────┘           
                │  ┌───────────────┐
                ├──┤  Dry curacao  │
                │  └───────────────┘
                │  ┌───────────────┐
                └──│   Cointreau   │
                   └───────────────┘

And then if you put in recipe "Orange curacao" as an cocktail ingredient, it will match any of child ingredients that you have in shelf, in this case: Dry curacao, Cointreau.

@karlomikus Yes, I understand that I can change recipes to specify the ancestor ingredient, but my request was specifically to create a system in which I could entirely avoid needing to change all the recipes themselves - this feels like a lot of extra work for each user to perform if (for instance) they import a large catalog of recipes and are completely unable to purchase a widely used specific ingredient (eg- Cointreau or Fernet Branca) and don't have access to that particular variant where they live (or always prefer another brand entirely).
