Sift the icing
sugar and gum tragacanth into a bowl and stand it
over hot water to warm it a little. Soak the gelatin
in 5 tsp water, the place in a saucepan with the
white fat and glucose.
Place over a low
heat until smooth, add the egg white then pour on to
the icing sugar.
Beat with an
electric mixer for 2-3 minutes, or until it becomes
elastic. (if you are beating by hand, you well need
to do it for at least 5-10 minutes. )
Keep it a plastic
bag in the refrigerator for at least 30 minutes
before use.
