Here's the Choc-o-Pav recipe:
Case
3 egg whites
3 tbsp cold water
1 1/4 cup sugar
1 tsp vinegar
1 tsp vanilla essence
3 tsp cornflour
Filling
100g cooking chocolate
2 eggs
1 tbsp whiskey (or rum/brandy etc... i tend to put a little bit more)
chopped walnuts (can omit and do fruit instead)
whipped cream
Beat egg whites until stiff, add cold water, one spoon at a time, beating constantly. Gradually add sugar, beating well, then mix in vinegar, vanilla and lastly cornflour. Pile on to wet greaseproof paper, form a round hollow in the centre and build up the edges. Cook 1 hour at 130C. Turn oven off, but leave in another 3/4 hour to cool.
Filling
Melt chocolate in bowl over hot water, beat in egg yolk, then liquor. Gently fold in the stiffly beaten egg whites. Pour into centre of cooled pavlova. Decorate with whipped cream and nuts or fruit or what have you.
It's really easy, and is a bonefide NZ recipe from a Mrs JE Landsborough of Wanaka that won a competition with it.
