Today’s Wonder of the Day was inspired by Rosie from IA. Rosie Wonders, “Why are pickles sour?” Thanks for WONDERing with us, Rosie!
We don't know for sure if zebras like pickles enough to fight over them, but we sure like them. They're one of our favorite green foods here in Wonderopolis. By themselves or on a juicy cheeseburger, you just can't beat pickles!
But what exactly is a pickle? Believe it or not, it's a cucumber that has been pickled.
Pickling — also called "brining" — is a way of preserving food by fermenting it in vinegar or a saltwater solution called "brine." The word “pickle" actually comes from the Dutch word pekel, which means "brine."
Like tomatoes, cucumbers (and thus, pickles) are technically fruits. You won't likely find pickles — even sweet bread-and-butter pickles — in a fruit salad anytime soon, though.
Most people treat them like vegetables since they are grown like vegetables and aren't naturally sweet. As a snack, pickles offer a good fat-free, low-calorie alternative to high-fat, high-calorie snacks.
