This is a great question for me since my speciality is “at home” Napoleon. (This was originally asked on Quora.) The memoirs tell us over and over that he liked to eat chicken. He liked broccoli but the strings kind of freaked him out because he felt like he was eating strands of hair. He liked dates since after his time in Egypt. Napoleon liked cherries. He ate too quick. He drank watered down Chambertin wine. He liked his coffee and his fruit flavored teas. He used licorice to fend off colds and he’d keep some of it with him in one of the many secret pockets inside his coat.
