In a large bowl, combine the flour, sugar, bicarbonate of soda, salt and raisins.
Grate the butter and cheese into the mixture and toss through.
In a small separate bowl, whisk the egg, buttermilk, thyme and honey together and add to the flour mixture.
Using your hands, knead the mix together until a soft dough forms.
Turn out onto a lightly floured surface and knead 3-4 turns or until it comes together and is slightly smooth. Shape into a ball, place into a greased bowl and cover it. Place the dough in the fridge for 1 hour.
Preheat the oven to 200ºC, gas mark 6, and remove the dough from the fridge.
Place on a lightly greased baking tray and score 1cm deep on the top into a cross using a sharp knife. Sprinkle extra cheese over the top.
Bake for 50-55 minutes or until baked through.
