50 free Peanut Butter trivia questions with answers — food & drink quiz, new questions added Aug 2026.
48 free Peanut butter trivia questions with answers. Peanut butter has a stranger history than the jar lets on. George Washington Carver did not invent it, the Aztecs beat everyone to it, the Dutch were banned from calling it butter, and the man who stopped the oil separating went on to invent chunky. This quiz covers the whole spread: the patents and health-institute origins, the brand battles between Jif, Skippy and Peter Pan, the PB&J, the fluffernutter and the Elvis sandwich, and the candy that grew out of it, from Reese's Penny Cups to Nutter Butter. There is peanut science too: why a peanut is a legume and grows underground, how the USDA screens for aflatoxin, and why Israeli babies who eat Bamba have fewer allergies. About a third of the questions are easy enough for a lunchbox crowd; the rest will test a food historian. Every answer has been checked against a primary source, mostly Wikipedia's peanut and peanut butter articles, and each question shows its citation.
