9 Surprising Things You Never Knew Lemons Could Do

But lemons also have some unexpected uses, too. Here are nine ways this citrus fruit can solve your trickiest kitchen dilemmas and enhance your meals.
1. Lemon Juice Prevents Your Fruits and Vegetables From Turning Brown
A few squeezes of juice can do wonders for avocados, apples, bananas, and peeled raw potatoes, since lemon juice is just acidic enough to prevent the oxidation that turns produce brown. According to research from 2014, this happens because of ascorbic acid.
“It’s found in all citrus fruits, including lemons, and helps keep other fruits and vegetables fresh by preventing browning,” says Grace Clark-Hibbs, RD, the owner of Nutrition With Grace in Portland, Oregon. “It does this by interfering with oxidation, the enzymatic reaction that occurs when the inside of an apple or potato, for example, is exposed to oxygen.”
To keep apples from browning, mix 1 tablespoon (tbsp) of lemon juice per 1 cup of water and soak the slices for about five minutes before rinsing. “This will prevent browning for about three hours if kept in a sealed container and will have minimal impact on the flavor of the apple,” Clark-Hibbs says.

2. Lemon Juice Keeps Rice From Sticking
3. Lemon Peel Keeps Brown Sugar Soft — and Saves You the Sifting
The juice isn’t the only useful part of the lemon; its super moist and flavorful peel can work wonders in the kitchen, too. Add a slice of the skin (with the pulp completely removed) to your box of brown sugar to keep it from clumping and hardening. “The molasses in brown sugar will evaporate over time, leading to dryness,” says Melissa Rifkin, RD, a nutritionist in Mount Kisco, New York, and a health expert for Juice Plus+. “The lemon peel can add some moisture and oils to help keep your brown sugar soft and slow the speed at which it may harden.” This way, you won’t have to do any sifting the next time you make a batch of cookies.
4. Use Lemon Juice to Cook Perfectly Hard-Boiled Eggs
Try brushing the eggshells with lemon juice before adding them to the pot to ensure that the shells won’t crack. This is an anecdotal hack rather than one that has a study supporting it, Rifkin says, but if you’re constantly dealing with shells that break before you’re ready for them to, it’s worth a try. Apply this technique before you enjoy the eggs in our Healthy Deviled Eggs Recipe.

7. Lemon Juice Enhances the Flavor of Your Food — No Need to Add Salt
A little bit of lemon can totally transform a meal, brightening up creamier dishes and balancing the flavor in seafood. “The acidic quality of lemon juice brightens up everything it touches,” Sackmann says. Clark-Hibbs adds that it also works well in enhancing bitter or sweet flavors. It packs so much flavor that it works as a sodium-free substitute for salt, says Lawrence. This is perfect for those with high blood pressure and anyone looking to cook healthier dishes without sacrificing flavor.
8. Lemon Juice Is an Everyday House Cleaner
The acid in lemon has an antimicrobial effect, which makes it a natural cleanser. “To create a cleaning solution, combine 2 tbsp of lemon juice with 1 cup of water,” Rifkin says. “You can also add 1 or 2 tbsp of vinegar for extra cleaning power.” Use this solution to clean cutting boards, windows, stovetops, and some countertops. Be careful around certain materials, such as a marble countertop, though. “The acid in lemon can damage some materials,” Rifkin says. Clark-Hobbs also likes to use lemons to clean the microwave or oven, where food and grease build up over time. “Place a single lemon wedge in a bowl of water, heat it up until the water is hot or boiling, then let it sit for a few minutes,” she says. “This will make wiping out either the microwave or the oven very easy. Plus, it will help eliminate any unwanted odors, leaving your kitchen smelling fresh and clean.”
9. Lemon Juice Can Repair Your Hair
You may be familiar with using lemon juice to lighten your hair, though that’s not recommended because it can lead to damage. But lemon can be used in other ways, such as in shampoo. Citric acid opens up the hair cuticle, which allows for deeper penetration. That’s why lemons are sometimes used to correct hair styling goof-ups, as a way to wash out wax or coloring.
