Beat the 6 egg yolks with the 60 g sugar until pale and fluffy.
Whisk the 6 egg whites to stiff peaks, and gently fold into the yolk mixture, then sift in the flour.
Heat the milk in a pan until hot but not boiling, then use two spoons to drop small dumplings of the sponge mixture into the milk, and poach for 2-3 minutes, until the dumplings float to the top.
Lift out the cooked dumplings with a slotted spoon, and leave to drain on a sieve.
Place a layer of dumplings in a buttered, heatproof dish, sprinkle with the walnuts mixed with sugar, then repeat with another layer of dumplings and walnut-sugar, until all is used.
Whisk the 5 egg whites to stiff peaks, and fold in the vanilla icing sugar.
Spread the meringue evenly over the top of the dish.
Bake low and slow in a 160°C preheated oven for about 15-20 minutes, until the topping is pale golden.
