ISO Beluga Lentils, dried or canned..
Where can I find these little beggars?
Bristol Farms carries dried beluga lentils packaged by Zurson in the dried beans section. These are excellent.
Whole Foods Markets often have them dried and/or canned as well, although I haven't used theirs.
Surfas also carries them and BH Cheese Store has them on occasion. Du Puy lentils are a good sub.
