Considering that I don't stop to eat while I ride, even if I did carry a spoon it would still be really hard to eat.
I'm going to try it tomorrow. See if I can ride no hands up a hill long enough to get the cottage cheese out of my pocket, open the tub, eat it with a spoon, replace spoon in pocket, replace top on tub, replace tub in pocket. Perhaps not while taking a pull, though.
