The question, in my mind, isn't whether chopsticks
can be used to make do with foods they aren't ideal for. For me, the question is more like, "If you had to eat a variety of global cuisines with nothing but a fork or nothing but a pair of chopsticks, which would be more universal?" Also, in the battle of fork vs chopsticks, the fact that a fork can be used a bit like a spoon counts in the fork's favor. That's one reason I think it's unfair to pit chopsticks against the whole suite of Western table utensils, because spoons are also a common item in Eastern cuisine. If we're eliminating spoons, they should be eliminated from both; and if we're eliminating spoons, I'd much rather be stuck with just a fork. As well, you can lift a bowl to your mouth and shovel the food with a fork even better than with chopsticks. If, for some reason, I
had to lift a bowl to my mouth and shovel, I would select a fork to do it.
p.s. You would eat the syrupy fruit pies (apple pie, cherry pie) with your hands, even if you had a fork right there? I mean, sure, okay. You do you, man.
