How to Tell if Kaffir Lime Leaves are Still Fresh
Identifying peak freshness and safe storage for Kaffir Lime Leaves.
Kaffir lime leaves stay fresh in the refrigerator for about 2–3 weeks when properly stored.
Kaffir lime leaves are prized in Southeast Asian cuisine for their intense, floral citrus aroma. Because they are hardy compared to delicate herbs like cilantro, they have a decent shelf life when kept cool. However, identifying the transition from 'vibrant' to 'wilted' is key to ensuring your curry or curry paste has that signature punch. Proper storage—such as wrapping them in a damp paper towel inside an airtight container—can significantly extend their usable window. When these leaves begin to darken excessively or develop a slimy texture, they have lost their aromatic potency and should be replaced.
Heads up: shelf-life ranges are estimates based on home storage. We make no guarantee of accuracy. When unsure, throw it out.
