1. Place the rice flour, cornflour, salt, Xanthan Gum and Baking powder in a large mixing bowl and mix thoroughly. It is advantageous to use an electric whisk or food processor to get a really good mix.

2. Rub the butter or margarine into the flour with your fingertips until it resembles breadcrumbs.

3. Add the mashed potato and mix until just combined. DO NOT ADD ANY FURTHER LIQUID. Briefly work the dough , shape into a ball, wrap in clingfilm and refrigerate for 30 minutes.

4. Remove the pastry from the refrigerator and knead by hand for approx. 2 minutes until smooth. Refrigerate again (uncovered) for 1 hour.

5. Remove from refrigerator and roll out on a floured surface as required.

Unlike some other gluten free dough, this pastry rolls out well and is excellent free form pastry recipes such as sausage rolls, pasties etc.

NB   It is important that the mashed potato be prepared well in advance and chilled (uncovered) for several hours beforehand.
