I adapted my old tried and true short crust pastry recipe to suit the thermomix. So if you don’t have a thermomix, just manually crumb the dry ingredients and butter together and then slowly mix in the wet and knead lightly.
2 cups plain flour
1 teaspoon baking powder
just over 1/4 cup water
Mix dry ingredients with butter for 10 seconds on speed 6. Add water slowly with measuring cup removed whilst kneading. After about 1 minute a ball of dough will form. Remove and roll out to shape.
Blind bake at 190 degrees until golden.
