I make a Szechuan peppercorn salt - I dry roast szechuan, black and white peppercorn together - equal amount - aka one part each . Once I start smelling 'that" smell - the aroma of the peppercorns - I add two parts kosher salt - roast another minute or two - usually the salt changes color just the slightest . I used to then grind this in a spice grinder but I've taken to putting the mixture in a pepper mill - works nicely.
