Caramelised turnip purée

Method

1. Melt the butter in a large pan over a medium heat. Add the turnip slices and gently cook for 10 minutes until they start to turn golden, stirring often and taking care not to let them burn. Keep turning them and let the butter slowly turn nut brown, adding the garlic for the final 2 minutes.
2. When the turnip slices are really soft, transfer them to a bowl. Clean and dry the pan, then add the sugar. Allow it to melt into a dark caramel (about 3-4 minutes; see tip), then add the cream and mix well – be careful as it may spit. Return the turnips to the pan and stir until well combined. Pour into a blender and whizz until smooth, then return to the saucepan. Add the sherry vinegar, then taste and season. Serve a couple of spoonfuls on plates, topped with the beef and jus.
