  Amount  Measure       Ingredient -- Preparation Method
--------  ------------  --------------------------------
   1      teaspoon      kosher salt
   1      teaspoon      ground hot red chile pepper
   1      teaspoon      whole peppercorns
   1      teaspoon      whole black [or yellow] mustard seeds
   3      whole         juniper berries -- (3 to 4)
   1      tablespoon    peanut oil
   1      tablespoon    apple cider vinegar
   1      tablespoon    dark brown sugar
   1      clove         garlic -- minced

Preparation:

Pound all this for a few minutes in a mortar (or pulse-process in a food processor) until the blend is a thick paste. Then thin it, if necessary, with a dribble of hot water until it is the consistency of bottled grainy mustard. Work the resulting rub evenly into the meat with the fingers and let it sit for about 30 minutes before putting it into the cooker. For beef ribs, omit the mustard seed and juniper berries.
