I took the time to gather all the new herbs and coffee beans then I had two of my Sims eat all of them to see what their moodlets would be. Eating them gives you a 8hr moodlet and using them on a fire keeps them for as long as the fire is burning and then 3 hours after your Sim has left the bonfire's vicinity.
