Clue: "She's like Aunt Jemima. Except she's white."
ANSWER: Mrs. Butterworth - although the brown bottle sometimes confuses people into thinking she's one of those offensive "mammy-doll" things, she is rumored to be a matronly, anglo grandmother type.
In reality, I'd say the clue may not be true, but that's not the point. It was said in a game, and we got it on the first guess.
