Combine all ingredients above in a saucepan and cook over a medium heat, stirring constantly until the temperature reaches 242 degrees (or a firm ball stage).  A firm ball stage is achieved by dropping a little caramel into a cold cup of ice water.  If it's ready it will make a firm ball. Add one cup of nuts, if desired.

Pour into a buttered 9 by 9-inch pan. Let it sit overnight on the counter. Cut into squares and wrap in waxed paper or place in tiny foil cups (similar to cupcake holders). Makes about 50-one inch pieces.
