4 large organic egg whites, at room temperature
115g Chelsea Caster Sugar
115g Chelsea Berry Flavoured Icing or Chelsea Icing Sugar

Preheat the oven to 100°C fan bake. Line 2 baking trays with baking paper.

Tip the egg whites into a large clean mixing bowl (not plastic). Beat them on medium speed with an electric hand whisk for 3 minutes. Turn the speed up and start to add the Chelsea Caster Sugar, a dessert spoonful at a time. Continue beating for 3-4 seconds between each addition. It's important to add the sugar slowly at this stage as it helps prevent the meringue from weeping later. However, don't over-beat. When ready, the mixture should be thick and glossy.

Sift a third of the flavoured icing sugar over the mixture, then gently fold it in with a big metal spoon or rubber spatula. Continue to sift and fold in the icing sugar a third at a time. Again, don't over-mix. The mixture should now look smooth and billowy, almost like a snow drift.

Scoop up a heaped dessert spoonful of the mixture and put on baking tray or put into a piping bag and pipe onto the baking paper. You can just drop them in rough rounds, if you prefer. Bake for 1 1⁄2 - 1 3⁄4 hours in a fan oven until the meringues sound crisp when tapped underneath.

Leave to cool on the trays or a cooling rack. (The meringues will now keep in an airtight tin for up to 2 weeks, or frozen for a month.) Serve two meringues sandwiched together with a generous dollop of softly whipped double cream or Chantilly cream.
