Mashed turnips with sage brown butter

1 Boil the turnips until cooked, then strain and mash them.

2 Meanwhile, put the butter into a medium-sized pot; it needs to be bigger than you think otherwise it will overflow.

3 Cook the butter over a moderate heat, after three minutes or so it should start to foam, the bubbling and hissing will stop and it will quieten.

4 Turn down the heat and allow it to become nutty around the edges.

5 Add the sage and the cinnamon and remove the pot from the heat. Allow to infuse for a few minutes.

6 Strain the butter on top of the turnips and season with salt, pepper and nutmeg.

7 Mix everything together. You can keep this warm or reheat it at your convenience.
