Storing whole lemons in the freezer is not typically recommended because freezing can alter their texture.
When you freeze a whole lemon, the water content inside expands and can cause the fruit to become mushy when thawed. This makes it less ideal for slicing or using fresh in dishes.
However, freezing lemon juice or zest can be a great way to preserve the fruit’s flavor for longer. You can juice the lemon and store the juice in ice cube trays or small containers, which allows you to use it as needed without worrying about waste.
Similarly, lemon zest can be grated and stored in the freezer, retaining much of its flavor for future use.
If you do choose to freeze whole lemons, it's best to use them for recipes where the texture won’t be as important, such as in cooked dishes or smoothies
Before freezing, wash the lemons thoroughly, and you can either freeze them whole or slice them for easier access.
Just remember that the texture will change, but the flavor will remain intact.
