A Simple Trick for Keeping Lemons Fresher for Longer
Lemons don't get much respect in the average refrigerator. After taking a slice or two to punch up drinks or add to a recipe, the remaining wedges can often be pushed out of view by incoming groceries and left to go to waste.
But the folks at Food52 have come up with a solution to get more use out of those lemons by keeping them fresher longer. Because citrus needs moisture in order to remain fresh, all you need to do is place your lemon in a bowl of water before putting it in the fridge.
Another idea: Put them in a sealed plastic bag and make sure you remove all the air to prevent mold growth. You'll get up to three months of freshness with this method. If your lemons are already cut into wedges, you can expect they'll last three to four days.
The "hack" also works for oranges and grapefruits. As for freezing, you can do that, too, but the resulting mushy fruit is probably best left for making juices.
