How Long Do Lemon Peels Last?
Lemon peels will start to lose their flavor after a few days, though how long lemon peels last depends on how you store them.
While you can freeze your lemon zest and lemon peels, they certainly won’t taste as good as they do when they’re fresh. Instead, repurpose your lemon peels before they go bad by transforming them into a preserved ingredient or use them in a recipe. For example, making marmalade or fresh lemon pepper can extend the shelf life of lemon peels.
