Preheat the oven
to 160'C/325"F/Gas 3. Line two baking sheets with
non-stick paper. Press the sugar through a metal
sieve into a bowl. Whisk the egg whites in a
grease-free bowl until very stiff and dry, then add
the sieved brown sugar, about 15ml/1 tbsp at a time,
whisking it in the meringue until it is thick and
glossy.
Spoon small
mounds of the mixture onto the prepared baking
sheets. Sprinkle with the walnuts.
Bake for 30
minutes, then leave to cool for 5 minutes on the
baking sheets. Transfer the meringues to a wire rack
to cool completely.
Cook's Tips: For an easy
sophisticated filling, mix 115g/4oz low-fat
soft cheese with 15ml/1 tbsp icing sugar. Chop 2
slices of fresh pineapple and add to the mixture.
Sandwich the meringues together in pairs.
