In a spotlessly clean bowl, whisk the egg whites with a hand-held electric whisk until stiff.
Tip the sugar onto a plate.
Carefully pull the rose petals off the flower heads.
Brush a rose petal with a little egg white, then dip into the sugar.
Shake off any excess and place on the greaseproof paper to dry.
Repeat with the remaining rose petals.
For best results, leave for 1,5 hours until completely dry.
Peel off the paper, then use the crystallized petals to decorate puddings, cakes and milk drinks.
Notes / Tips / Wine Advice:
For rose syrup cordial, place 450 g granulated sugar and 225 ml (7½fl oz) water in a heavy-based saucepan and bring to the boil, stirring continuously until the sugar has dissolved. Add the juice of ½ lemon and simmer for 5 minutes. Stir in 100 ml rosewater and simmer for 4–5 minutes. Leave to cool in the pan, then pass through a sieve into a sterilized bottle or jar. To serve, put a few ice cubes into a glass, add 2½ tablespoons rose syrup and top up with cold water. (The cordial can also be stored in the refrigerator for 4 weeks.)
