Preheat your oven to 350F. Place the chicken breasts on a board and with a sharp knife, slice a pocket along the length of the breast.

Use your hands to form the haggis into two long sausages and tuck each inside the breasts.

Lay 3 rashers of bacon on two pieces of plastic wrap, overlapping the rashers. Place the chicken breast on each and carefully rapping each breast, covering as much as you can, tucking the ends underneath.

Generously brush the chicken with the melted butter and season with salt and pepper.

Wrap the chicken breasts in tin foil and place on a baking sheet. Bake for 20 minutes, then open up the tin foil parcel and back for another 10 minutes.

Let rest for a few minutes. When ready to serve, slice across the width to expose the stuffing, plate and then spoon on the whiskey sauce

Combine the stock and the whiskey in a small pan, and bring to a boil, reduce the heat and reduce until half the volume.

Stirring constantly, add the mustard and cream so that is well combined. Melt in the butter which will help thicken the sauce.
