Preheat the oven to 140°C/275°F/Gas mark 1. Line
two baking trays with baking parchment.
-
Draw a
23cm/9in circle on one sheet, using a plate as a
guide. On the other sheet draw an 18cm/7in
circle. Turn
each sheet of paper over.
-
To make the meringue, whisk the egg whites in a
large bowl until stiff but not dry. Gradually
whisk in 250g/9oz of the sugar, a tablespoon at
a time, whisking well after each addition until
the meringue is stiff and very shiny.
-
Whisk in
the spice
with the last tablespoon of sugar. Carefully
fold in 100g/4oz hazelnuts, and the
white and plain chocolate.
-
Spoon the meringue on to the baking parchment
circles, then spread neatly into rounds using
the guidelines. Bake for 2 to 2 1/2 hours until
dry and the
undersides are firm when tapped.
-
Turn the oven
off and leave the meringues to
cool in the oven.
Put the remaining hazelnuts in a small
heavy-based pan with the remaining sugar. Heat
over a gentle heat until the sugar melts.
-
Continue cooking until the mixture caramelizes
to form a rich golden brown color, then pour on
to a greased baking tray. Leave to cool and
harden.
-
Pour the caramel mixture into a polythene bag
and crush with a rolling pin until
it forms coarse praline.
Spread the double cream evenly over the large
meringue and cover with the
small
meringue round.
-
Sprinkle with
the praline and dust the top of the cakes with cocoa powder before serving.
