- 1.4 kg (3lb) floury potatoes, such as Maris Piper, peeled and cut into large chunks
- 900 g (2lb) parsnips or celeriac, peeled and cut into large chunks
- 50 g (2oz) butter
- 4 level tbsp snipped chives or freshly chopped flat-leafed parsley
- 200 g tub crème fraîche
- 3 level tbsp Dijon mustard
- Step 1
Simmer the potatoes and parsnips or celeriac in a large pan of salted water for 20-25min or until tender.
- Step 2
Meanwhile, put the butter in a pan and heat gently to melt. Bring to the boil, turn off the heat and skim off the white surface with a slotted spoon. Pour butter into a jug, discarding the milky substance at the bottom. Add the herbs and season well.
- Step 3
Drain the vegetables. Return them to the pan and put over a low heat for 1-2min to dry. Put in a free-standing food mixer with a flat beater attached and beat on a low speed (or crush with a potato masher in the pan). Beat in the crème fraîche and mustard and season well. Keep warm. Shape into ovals (see COOK'S TIP, below), spoon into a warmed serving dish, then drizzle with the herb butter.

Cook's tip
Shaping the potatoes into portions looks impressive and makes it easy for everyone to help themselves. To create these oval shapes (known as quenelles) take two large serving spoons. Hold one in each hand and take a scoop of mixture, then scrape one spoon against the other to lift the mixture off. Repeat the process twice to make a neat oval shape and carefully push on to a serving dish.
