Add the lemon juice a little at a time, stirring until you have a crumbly but not sticky mixture.
Add a few drops of peppermint extract and combine.
Knead with your hands until your mixture is smooth and forms a ball (add a little more lemon juice if it's too crumbly but not too much or you will end up with a sticky mess - if you do end up with a sticky mess add a little more icing sugar - don't get caught in a loop!)
Lightly dust your work surface and a rolling pin with icing sugar and roll out your dough until it's about 5mm thick.
Cut it into shapes using cookie cutters, we used hearts, snowflakes and stars.
Place on baking parchment and leave to dry for at least half an hour.
