Gradually sift in half of the icing sugar, stirring with a wooden spoon.
Add the peppermint oil and continue to add the remaining icing sugar, mixing until a smooth, firm paste forms.
You may not need all the icing sugar.
Roll the paste into a long sausage about 3 cm in diameter, then cut into 1 cm slices.
