Drain the barley and place in a pot. Cover with water, season with salt and bring to the boil. Simmer for 30 mins, or until just soft. Drain and add a tablespoon of butter on top. Keep in a warm place.
Meanwhile, heat a frying pan on a medium heat and season the venison with salt and pepper. Fry in a trickle of rapeseed oil with a knob of butter and some thyme. Baste as you go, cooking for 5-10 mins until golden brown, according to how rare you like your venison.
Allow the venison to rest for at least 5 mins before carving – give it a quick flash under the grill to make it piping hot again if you'd like.
Cut the cabbage into strips and wilt it down in a pot with a knob of butter and salt and pepper. I like it quite crunchy.
To serve, carve the venison and arrange on a plate. Sprinkle with the barley and drape the cabbage over and around the meat. The rich flavour of the venison loin fillets pairs perfectly with grains and greens. Delicious and simple - one of our top seasonal recipes for autumn.
