The above recipe is from a very old recipe booklet put out by Fielder's Cornflour. I've added some notes below for clarification. I believe the Fielder's cornflour is now sold under the White Wings brand???

Notes:
In the recipe booklet, it said a glass cup is used for cup measurements, whatever that means?
3/4 cup Fielder's cornflour = 100g
3/4 cup sugar = 125g caster sugar
1 dessertspoon = 2 teaspoons
carb. soda = bicarb. of soda = baking soda
