Tweaked to complement fish and green beans as well as red meat, the current rub is the product of "cryogrinding," which is what you do when you have barrels of liquid nitrogen handy. The ChefSteps guys freeze juniper before drilling it down to the exact right size for flavor release; coriander, sea salt, dark demerara sugar, black peppercorns and red chiles are also individually ground for optimal flavor.
What's wrong with most rubs, according to Modernist Cuisine thinking, is that interesting ingredients are blitzed together in a massive grinder without regard to texture. That's not the case with this subtly sweet, piney rub.
