In a small pan heat the oil. Add the onion, garlic and ginger, cook for a few minutes until softened. Add plums, apple, fruit juice and sugar. Simmer for about 10 minutes until reduced and slightly sticky.
Season the lamb steaks. Preheat a grill or griddle plate and cook lamb steaks for about 4-6 minutes each side (depending on thickness of steak).
When cooked place on a plate, add a small knob of butter to the top of each steak and allow to stand for 3-5 minutes.
Serve steak with buttery juices, Autumn Chutney and seasonal vegetables.
