I think what's really strange about this is that it is written as though there is just one kind of onion, whereas any connoisseur will wax poetic about the difference between Walla Walla Sweets, Vidalias, Mauis, Texas varieties, generic yellow, white, and red onions, shallots, leeks, scallions, pearls, cipollinis... so does the law just cover generic yellow onions?
