It recently dawned on me that onions must be one of the very most widely used and beloved of all vegetables. (Yes, I took a Ph.D. from Dartmouth in Obvious Studies.) It seems that almost every major cuisine on the planet makes liberal use of them. And then I asked myself, "Khan, which cuisine uses onions the most?" I had not a definitive answer. So now I ask the question of you all and will wait with bated, onion-scented breath for your answers.
