Just found this recipe for syn free meringue online, sounds easy enough and the OP says:'Think I'm going to be making these quite often!!'
Ingredients:
2 egg whites
90g Splenda (1 jar)
Directions:
Preheat the oven to 130°c.
Whisk up the egg whites until they stick to the bowl when you turn it upside down. Gradually whisk in the Splenda a little at a time.
Cover a baking sheet with baking paper (I find it's a lot easier to stop them sticking).
Spoon dessertspoonfuls of the mixture (using two spoons to shape them) onto the baking sheet. Bake at 130°c for one hour. Then turn the oven off, but leave the merinuges in the oven until it is completely cold (overnight if you're cooking them in the evening). This way they dry out completely and don't have the sticky bit in the middle.'
