So I work with a jew, who knows a jew who knows another one who through the global jew conspiracy network knows a jew that works at a famous Montreal deli. That's apparently the story, and here's the recipe that came with it.
Mix together 2 parts kosher salt, and 1 part each of: white pepper, black pepper, mustard seed, dill seed, coriander seed, coarse garlic, coarse dried onion and hot pepper flakes. Dump the mixture into a pepper grinder and set it for a coarse grind.
I picked up the ingredients for this, and decided to give it a try on a couple nice porterhouses. HOLY FACK
