At some stores, you might have to buy three or more at one time to get the best price. However, if your lemons go bad before you use them, then it's a lemon of a deal. Now, you can buy your lemons and enjoy all of them too!
It makes perfect sense because the citric acid, that is released when they are cut open, keeps the slices preserved in a healthy, natural way. And the best part is they are already cut and ready for use! Just make sure you wash your lemons well before you slice them and keep them stored in the refrigerator. I used the 16 ounce jar, pictured below, to hold the slices of two large lemons, and it's one of my favorite visuals when I open the fridge.
