I'm not sure if this was discussed or if it is a future feature, but will we be able to make/discover our own recipes? Say, for example, that I have all the blending and cocktail crafting skills. Can I go on to mix my ingredients on my own, with no magically rocky suggestion, to discover a new cocktail?
I'm thinking that the implementation may be something like a large database of cocktails, with a matrix of how different values of fruit, produce, juice, hooch, spice, and ice can be combined to make these cocktails; the catch is that none of this information is known beforehand. Suggestions could be made once a month for new items to be added to the database, with no hint being made of the ingredients that go into them.
The more intensive and possibly impossible solution would be to allow any edible product to make a recipe, but let the players "make" personal recipes by writing notes that can be permanent saved in a special case (recipe box or some such). The basics of such a system would be that the edibles all have certain properties, and a particular algorithm can calculate the food's properties (color, container, mood, energy, xp, bonus mood, etc.) for you.
