Add oil to a frying pan, along with the onion and sear each side of the meat about 2 - 3 minutes per side. Chop a mixture of root veg into chunks
Move it into a slowcooker
In a different dish, stir together the red wine, soy sauce, sugar and stock and pour over the meat.
Add the vegetables and cook on low heat for 6 hours
Before serving, pour the stock into a saucepan. Put two tablespoons of corn flour and 4 tablespoons of stock together in a bowl and mix it together to make a paste. Add more tablespoons of stock till it forms a runny liquid and there are no lumps then pour it into the saucepan with the rest of the stock. Leave for about 10 minutes till it thickens up then add the meat back in
Serve with rice, Yorkshire puddings or other sweet breads
