Cambridge Dry Rub

    1/4 c  Brown sugar                         2 tb Cumin
      2 tb Salt                                2 tb Paprika

  In the top half of a double boiler set over simmering water, combine all
  the ingredients.  Cook for about 20 minutes, stirring every 5 minutes or
  so, until the sugar begins to melt and mixture thickens.  Remove from the
  heat and let the mixture cool to 100 F.

  Pass the mixture through a sifter.  Use immediately or store in a cool,
  dark place for several months.
