1. Prevent Browning: A few squeezes of juice can do wonders for avocado, apples, bananas, and peeled raw potatoes, since lemon juice is just acidic enough to prevent the oxidation that turns produce brown.


2. Stop Rice From Sticking: Have a problem with clumpy rice? You’re in luck – adding a few drops of lemon to your cooking water helps prevent the rice from sticking together. Added plus? The lemon juice will also whiten your rice and keep it looking great on the dinner plate!

3. Keep Brown Sugar Soft: 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.

4. Crisp Your Lettuce: No need to toss that limp lettuce! A little lemon juice and water can help bring your leaves back to life. To crisp up limp leaves, soak them in a bowl of cold water and ½ cup of lemon juice, then refrigerate for about an hour. The leaves will come out revived and ready for eating. Try it out on a simple green salad. 

5. Cook Perfect Hard-Boiled Eggs: Even if you’ve mastered perfectly hard-boiled eggs, try brushing the eggshells with lemon juice before adding them to the pot for a little added insurance. The lemon juice helps keep the shells from cracking while they cook, and it also makes them easier to peel once they’re ready to eat.



6. Tenderize Meat: Lemon juice is a great meat tenderizer; the acidity gently breaks down the fibers in meat, leaving it scrumptiously fork-tender.

7. Enhance Flavor: Last, but certainly not least, lemon’s yummy flavor can totally transform a meal. It brightens up creamier dishes, balances the flavor in seafood, and is a great sodium-free substitute for sprinkling on salt.
