Preheat oven to 400 degrees. Beat egg whites with pinch salt 5-6 minutes. Gradually add sugar, vinegar and vanilla. Beat until stiff peaks form. Use an oven-proof large plate, or turn a 9 x 13 pan upside down. Wet the surface, then spoon meringue on top, smoothing center and raising the edges a bit. Put in oven and turn temperature down to 250 degrees. Bake undisturbed for 1 1/2 hours.
Whip cream, and when Pavlova has cooled, heap cream on top. Garnish with fruit; sweeten cream and fruit to your taste. You might like mocha or chocolate cream, garnished with chocolate shavings! Serve in small pieces as it is very rich.
