Pre-heat the oven to 200°C/fan 180°C/gas mark 6.
Place the Prozero and psyllium husk in a bowl and allow to stand for 5 minutes until the mixture thickens.
In a separate bowl, place the butter, Fate low protein all-purpose mix and baking powder.
Rub together with your fingertips until you get a sand-like texture.
Add in the Sainsbury’s deliciously free from grated cheddar-style and mustard to the mixture and mix well.
Add the liquid mixture into the bowl and mix to form a sticky dough.
Turn the dough out onto a lightly dusted surface and knead for 1 minute.
Roll the dough into a ball and flatten the top down to an approximate depth of 2cm.
Using a cutter, cut out 4 scones.
Transfer the scones to a lined baking tray and brush the top of the scones with oil.
Bake in the oven for 20 minutes until golden brown.
Leave to cool fully on a wire rack.
