offerings for the big three

I just spent 6 hours on my feet painting this for Hades, Poseidon and Zeus and I am going to give it to them tomorrow. Does anyone know any beverages or food they might enjoy with it? They share an Altar on my bookshelf and I am wanting to give them something new since I just moved them to their new location. I don't want any of them getting mad or feeling outshined in anyway. Any advice is appreciated!
