Spread the hazelnuts on a
baking sheet and toast in a preheated oven at
180°C/350°F/ gas mark 4 for 15 minutes until the
skins loosen.
Rub off the skins in a tea
towel and chop the nuts finely. Put the egg
whites and icing sugar into a bowl and whisk
until the mixture forms stiff peaks.
Gently fold in the chopped
hazelnuts and the lime and lemon rinds.
Line baking sheets with
nonstick baking parchment or oiled foil and
drop large spoonfuls of the meringue on to the
sheets, shaping into tear shapes with the end of
the spoon.
Reduce the oven to 150°C/300°F/gas
mark 2 and bake for 45 minutes. Allow to cool
and serve with raspberry sauce.
