Onion and walnut compote

Method

1. Heat the oil in a large, heavy-based pan over a medium-low heat. Add the onions, season with salt and cook for 15 minutes, stirring occasionally, until softened and lightly caramelised.
2. Stir in the honey and bubble for a few minutes until reduced. Add the vinegar and cook for 5-8 minutes, stirring occasionally until sticky and well reduced. Stir in the raisins and walnuts and season to taste. Serve warm or at room temperature.
