Pink, Green and White Mints
Whisk the egg white in a bowl until stiff peaks form. Slowly whisk in the lemon juice, peppermint and icing sugar to a stiff paste.
Divide into 3 and knead a few drops of food colouring into 2 pieces.
Place the peppermint mixtures onto a work surface dusted with icing sugar and roll out thinly.
Use a small cutter to cut out rounds and place them on a tray. Chill for 2 hours, until set.
