Kenji Lopez-Alt answers another food question for us. This time, does Mexican Coke, the one in a glass bottle, taste better. What does he decide? You’ll have to read to find out.

More than once in the past, I’ve discovered that the brain has a powerful effect on the taste buds. Free-range eggs taste better? Nope. Darker colored eggs taste better. Is New York pizza better when made with New York tap water? Nope. At least my panel of experts couldn’t tell the difference. I’ve done tests where I’ve fed an entire room full of people two batches of identical carrots, labeling one as organic and the other as conventional. Unsurprisingly, they unanimously pick the carrots labeled organic as superior in flavor every single time, even when they are two halves of the same carrot.
