I think the new Graham Nardone interview gave us some interesting information: Sims Community: Sims can now make ice cream. There are 30 flavours and a variety of toppings and garnishes. It seems some combinations can yield unexpected results. Could you give us one example? Graham Nardone: The hidden combinations are the result of pairing a particular trait with certain toppings and garnishes. For example, Foodie Sims enjoy something a little more exotic like edible flowers and raspberry sauce on their ice cream. One unique combination is for Sims with the insane trait though. If you happen to combine the nuts topping with nuts as a garnish… well, it has a tendency to get them pretty excited!
