Ingredients
  

  • 800g (28oz) potatoes peeled and cut into chunks
  • 35g (⅛ c) butter
  • pinch nutmeg
  • salt
  • 2 egg yolks
  • melted butter or egg yolk to glaze, optional

Instructions
 

  • Cook the potatoes in boiling water for 15-18 minutes until tender.
  • Drain and return to the pan.
  • If cooking straight away, preheat the oven to 200˚C fan /220˚C / 392˚F convection / 425˚F
  • Line two baking trays with baking parchment
  • Return the pan to the heat and cook for 1 minute, to evaporate any moisture, shaking the pan every so often.
  • Stir in the butter, nutmeg and season, then mash.
  • Pass the mashed potato through a sieve, using the back of a spoon to push it through.
  • Let the mixture cool for a few minutes then stir in the egg yolks, then place in a piping bag fitted with a 2 cm/ ¾" star nozzle.
  • Tip: place a tiny amount of mashed potato in the 4 corners of your tin, between the tin and baking paper, this will stop the baking paper from moving when you pipe on it.
  • Pipe 26-28 walnut sized mounds onto the trays (like icing a cupcake).
  • Gently brush each mound with either a beaten egg yolk or a little melted butter.
  • Place in the preheated oven and bake for 15-20 minutes, turning the trays around after 10 minutes, until golden.
  • Serve immediately.

Notes

To Freeze: Place the tray of piped duchess potatoes in the freezer. Once frozen, remove to a container or bag. Cook from frozen, adding an extra 3-5 minutes.
Glaze:
Egg yolk: the duchess potatoes are shinier when cooked, the taste is slightly eggier (no surprise there.)
Melted butter: Still goes golden and crisp, but less shiny. Has a slightly richer taste.
Nutritional information is per duchess potato, based on making 26 potato mounds.
