There is a large number of food items to be prepared, but the list of craftable drinks is quite small by comparison. I would love to have more drinks to make, especially some that are of middling value which would be quite useful (but not overpowering) for younger players, who need to keep their mood high.
Possibles:
Hot tea (Tea leaves purchased from vendor and mixed with water, then heated in Saucepan?)
Iced tea (as above but with ice added)
Arnold Palmer (iced tea plus lemon[ade] juice), would need a different name like "Legendary Golfer"
Hot chocolate
Cream (a new process using butterfly milk - would also be useful in some food recipes and sauces)
Irish coffee (coffee, cream and hooch)
A way to carbonate the juices, like Fizzy Fruity Juice or Fizzy Lemon Juice
