What is the enhancement in mind? How should it look and feel?
Fairly straight forward and simple: The ability to create recipes that will output the configured food item in the craft box, with configurable output amounts.

Please provide any additional information below.
Ideally, the creation side would be GUI based (like how RPGItems does it's recipes), and if possible also require it to match meta data on the items. That way a server owner could configure a brown clay block to be "Chocolate" with a lore of "Used in food recipes." and the plugin wouldn't accept a vanilla clay block that someone anvil-named "Chocolate" but was missing lore. Even just a basic non-meta supporting release to start with, would be amazing.

Execution could simply be that the items are created as usual in the config, and then any that you want to enable a recipe for a specific item you could type:
/consumables recipe <food name>
Which would create the recipe for an item w/o one, edit the recipe for one already made, or simply view the recipe. (Note: A blank recipe would be treated as invalid, and thus removing the recipe being enabled for that food.)
Also, naturally, you would need the following, should you want to remove an food's recipe quickly:
/consumables delrecipe <food name>
Finally, any food with a recipe should have a config option to remove from the selection GUI (except for players with the Admin permission, so they can access all of the available foods), as that sort of defeats the purpose of the recipe in the first place; however, some servers may still want them to show up that way, thus the configurable choice.

I think the inclusion of that, would take this from a great plugin, to an awesome one! ;)

Hmm I feel that this would be a cool feature but.. many plugins already do this and as long as the item representing the consumable has the consumable's display name and lore then it will act like the consumable. I will think about adding this but it is definitely already possible to do with a custom crafting plugin.
