Step 1

Mix together the icing sugar, egg white, lemon juice and peppermint oil until you have the texture of pastry. Knead well so that the mixture is smooth, then roll out on a work surface lightly dusted with icing sugar to a thickness of 1cm (½in).

Step 2

Cut out rounds with a 2½-4cm (1-1½in) cutter – or for fun, try different shaped cutters such as stars, hearts and moons. Pop them on a piece of greaseproof paper and decorate with the crystallized violet and rose petals. Leave to harden for 12 hours or overnight.
