4      tablespoons   salt
   1      tablespoon    black pepper, freshly ground
   1      tablespoon    lemon pepper
   1      teaspoon      onion salt
   1      teaspoon      mild Chili powder
   1      tablespoon    cayenne pepper
   3      tablespoons   brown sugar
   1      teaspoon      white pepper
   1      tablespoon    thyme, dried
   1      tablespoon    rosemary, dried
   1      tablespoon    cornstarch

In the top of a double boiler, combine all ingredients accept the cornstarch. Heat over simmering water until the ingredients are warm to the touch (about 72°C).  Stir continuously during heating.  As the sugar dissolves, it may form a crust.

Transfer the heated mixture to a glass bowl and cool to room
temperature.  Break apart the crusty mix and rub the mixture
between your fingers so that it becomes granular again.  Add the cornstarch and stir to mix.  Use immediately or keep in a glass jar with a tight-fitting lid.  Store in a cool dark place.
