My freshman year of college, I had a dormmate who claimed she had never seen a bagel before. She was from California.
Upon reflection, what probably happened is that she had seen bagels, but had assumed that they were donuts. Now, you and I both know that donuts and bagels are COMPLETELY different deities, each hole-y in their own divine ways. Donuts are usually soft and sweet, their top surface an edible canvas for an array of saccharine glazes and toppings. Bagels are firm, chewy, and often serve as vessels for any manner of spreads, schmears, and brined seafood.
But do donuts and bagels really look that different when you take away their color? Test yourself with these black and white photos to find out whether you can really see the difference!
