Pre-heat the oven to 200°C | 400F | gas 6. Grease a baking tray with 1 tbsp of the vegetable oil and set to one side.
In a large mixing bowl, sift together the flours, salt, baking powder and the caster sugar.
Rub the margarine into the flour mix until they are no long distinguishable.
Create a well in the centre and pour in the rest of the vegetable oil and the buttermilk (make sure you reserve 1 tbsp of the buttermilk).
Use a spatula to bring the dry and wet ingredients together gradually until you have a moistened dough.
Turn the dough out onto a lightly floured surface and knead gently for a minute until smooth.
Shape into a loaf and arrange on the greased baking tray. Create a cross in the top of the loaf using you finger and brush with the remaining tbsp of buttermilk and dust with a little strong bread flour.
Bake in the centre of the oven for 25 minutes and then reduce the heat to 180°C | 350F | gas 4, turn the loaf and bake for a further 20-25 minutes.
