Tip the blueberries into a pan. Add the juniper berries into a mortar and lightly crush them with a pestle. Or, tip into a bowl and crush with a fork. Add to the blueberries with a pinch of cloves.
Add 2 tsp of honey to the pan with 2 tbsp cold water. Gently heat for 2-3 mins till the blueberries have started to break down and release their juices. Cover and set aside.
Shred the cabbage, discarding any really thick pieces of the core. Finely slice the mushrooms.
Rub 1 tsp olive oil into each of the venison steaks. Season with salt and pepper.
Warm a griddle or frying pan over a high heat. When it’s hot, add the steaks. Fry for 2-3 mins on each side, or a few more mins for well done steaks.
Put the steaks on a plate. Cover loosely with foil. Leave them to rest for 10 mins. Fill a pan with boiling water. Cover and bring back to the boil.
Add 1 tsp oil to the frying pan. Add the mushrooms and season. Fry over a medium heat for 5-6 mins till soft. Stir every so often. Finely chop the chives.
While the mushrooms cook, add the cabbage to the pan of boiling water. Simmer for 3-4 mins till tender. Drain well. Serve the steaks with the mushrooms, cabbage and spicy blueberry sauce. Scatter with the chives to garnish.
