TIS, It's smoked salmon. Mr. Babe has a smoker, and he used to actually make his own sometimes, but hasn't done it in years.

Really good delis have excellent lox, but most of the bagel places out here buy some cryo'd stuff, which I can buy myself at Costco. Actually, I often buy mine at either Costco or Trader Joe's. The problem with Costco's is that it's such an enormous package that it goes bad before we can eat it all.
