Loosely suggested by me in Nutrition Test thread:
Hot Cuppa could be moved being evolved recipe - it fits as one, as the current recipe is common for both tea and coffee, and it would allow to maintain use of a whole tea bag while adding drainable coffee idea:
The evolved recipe would also make idea of making sugar optional possible, by making sugar one of the (optional) ingredient while allowing use of additional recipe ingredients, such as milk (or in future/mods maybe other kind of sweeteners and spices)
One possible problem would be mixing coffee and tea in one dish (I don't mind using two doses of coffee or two tea bags - it seems natural if you want a stronger drink), but hey it's survival, so do what you want if you're short of water and desperate for a drink :P. Another possible problem is that I don't know how evolved recipes can handle stress reduction (they already get unhapiness and boredom reduction already anyway)
