This is a bit tricky but well worth it, if you want a good laugh with your Mum this is a good start.
Needs:
Vegetable oil, Greasing
50g or 1/2 cup icing sugar (confectioner's)
50g or 1/2 cup corn flour (cornstarch)
2 Egg Whites
400g or 2 Cups Caster Sugar
15ml or 1tbsp glucose syprup (light corn syrup)
375 ml or 13oz cold water
60ml or 4 tbsp powered gelatine
5ml or 1tsp vanilla
3 drops of green color
3 drops of yellow color
1. Grease baking tray, Combine icing sugar and corn flour in large bowl. Put it through a sieve into another bowl. Liberally sift some of the mixture on the baking tray. Set aside.
2. Whisk the egg whites until they form peaks (electric whisk works much better and faster). Set aside, when ready to use them give them an extra whisk as they separate slightly.
3.Combine caster sugar, corn syrup and half the water in a small pan over low heat, stir until sugar dissolves.
4. Bring syrup to boil and boil until it reaches the hard boil stage (130c/266f)
5. Meanwhile, soften the gelatine with the remaining cold water in a small pan, off the heat. Just before before the sugar syrup reaches the hard-ball stage, place the gelatine mixture over a low heat and stir til dissolved.
6. When the syrup reaches the correct temp and the gelatine has dissolved, combine the two. Stir in vanilla extract.
7. While whisking the egg whites with electric mixer pour in the syrup and gelatine mixture with a slow and steady stream.
8. Whisk mixture on high for 7 minutes or until it holds soft peaks.
9. Divide the mixture into two bowls and add a different color to each one. Using the electric whisk, mix (both) until almost stiff.
10. Pour one part onto prepared baking tray and and spread quickly.
11. Quickly spread the other part on top. Allow to set for 5 hours.
