I'm just about to christen the Kenwood mixer my husband gave me for Christmas but amazingly, I've never made a pav before. I need the perfect recipe and any hints or tips. The eggs are already out getting to room temperature!

1tsp vinegar, 2tsp cornflour. Preheat oven to 110c. In a latge bowl (not plastic) beat the egg whites until soft peaks form. Gradually add sugar a tsp at a time. Mixture should be getting glossy, thick & shiny with each addition & process should take approx 10 mins. Beat in vanilla, vinegar & cornflour. Spoon mixture on baking-paper. Bake 1&1/2hrs until dry, crisp & lifts easily off the paper. Cool on a wire rack.
