Combine sugar, water, corn syrup and salt in a large heavy pan. Heat and stir
until sugar crystals are dissolved, then stop stirring. Bring to a rolling boil
and wash down the crystals, then add the cream of tartar. Boil rapidly to the hard
crack stage on a candy thermometer.
Pour two-thirds of the syrup out quickly onto a slab or greased flat pan.
Pour the rest into a buttered glass pie pan, and do not move until partly set.
Turn the edges in on each portion and add flavoring to each - about 6 drops of
oil to the large portion and 3 to the small.
Add food coloring to the small dish. As soon as possible, start to pull the portion
in the large container until pearly-colored. (It will be very hot - butter your
hands and set it down when it gets too hot!) Form it into a ball.
Meanwhile gather up the colored portion and form it into a rope and wrap it around
With one person on each end, start to stretch and twist the ball in opposite
directions to form a long rope with the traditional stripe.
Cut into lengths as necessary.
When the desired diameter is achieved, cut and form into canes (roll it on the
board to get it smooth). If it gets too cold to work with, put on a wooden breadboard
in a warm oven to soften.
