Black lemon is a spice used in Middle Eastern dishes. It is made by boiling fresh lime fruits in salt water and sun drying until the insides turn black. The outside color varies from tan to black. Dried lime is sold whole or ground.

Dried limes are usually used in legume, seafood or meat dishes. They are pierced, peeled or crushed before adding them to the dish. After cooking they become softer and edible. They can also be powdered and added to rice dishes. Powdered black lime is also used as an ingredient in Persian Gulf-style baharat (a spice mixture which is also called kabsa or kebsa). It is a traditional ingredient of Arabic and Persian cooking.
