This is the kind of study that I adore: Researchers at the University of Oxford decided to test if the choice of a spoon affected the flavor and other qualities of food. Turns out it does!
Spoons made of metal or plastic changed perception of yogurt’s quality and density – and not in the way I’d expect. Black spoons and white spoons had different effects. You have to read the article over on the Smithsonian blog. It’s wonderful.
