These can be pale or mottled green-brown in color with a glossy exterior. They have a robust, somewhat peppery flavor. Green lentils generally take the longest to cook, upwards of 45 minutes, but they keep a firm texture even after cooking. This makes them ideal for salads and other side dishes. Look for Lentilles du Puy, Puy lentils, or French Green lentils.
Le Puy green lentil
The Le Puy green lentil is a lentil cultivated from the Lens esculenta puyensis variety.
The “Le Puy green lentil” is protected throughout the European Union according to its Protected Designation of Origin and in France as an AOC. In the European Union, the term may only be used to designate lentils that come from the region of Le Puy (most notably in the commune of Le Puy-en-Velay) in France. These lentils are claimed to have gastronomic qualities that come from the terroir.
