Caramelised celeriac mash with spiced walnuts

Preheat the oven to 180°C/gas mark 4

Place the honey, cinnamon and nutmeg in a small saucepan and heat until the honey begins to bubble. Add the walnuts, stirring to coat, and season with salt. Spread the walnuts on a baking tray lined with parchment paper and bake for 10 minutes, stirring every few minutes. Allow to cool, then finely chop

For the celeriac purée, heat the butter in a large saucepan over a moderate heat. When hot, add the celeriac and season with salt. Cook for 20–25 minutes until the celeriac is soft and has a deep golden colour

Add the milk to the saucepan and bring to a simmer for a few minutes. Scrape the bottom of the pan well, then transfer everything to a blender. Blend until smooth, adding a little more milk if needed

Taste and adjust the seasoning as necessary. Serve hot with the chopped walnuts on top
