Lex made these at school last week, and having brought the recipe home was desperate to make them with me. So we did.
100g plain flour
50g grated cheese
1/2 tsp salt
1/2 tsp mustard powder
50g mashed potato
1 tbsp water (I had to use about 2)
Blitz the flour, salt, mustard and butter till they resemble breadcrumbs. Then add the potato, cheese and water and mix to a dough. Roll out till about the thickness of a £1 coin then cut into strips. Twist the strips and lay on a baking sheet, brush with a little milk and bake in a hot oven for 10 mins. Leave to cool and then eat. Delish!
