Peel the potatoes and cut into even chunks. Put in a large pot of cold salted water and bring to a boil.
Boil for 15 to 20 minutes until the potatoes are fork tender. Darin and set aside.
Put the pot back onto a low / medium heat.
Add the butter, milk, salt, pepper and wholegrain mustard to the pot. Allow the butter to melt and stir everything together.
Add the potatoes back to the pot, mash and serve.
- Cut the potatoes into similar sized pieces so that they cook through evenly.
- Add the potatoes to cold water, not already boiling water. If added to boiling water, the middles will not cook fully through.
- Salt the water you cook the potatoes in, this will help to add flavor right from the start of cooking.
- Use a potato ricer to get really fluffy mashed potato. Rice the potatoes straight into the mustard butter mix in the pot and stir together.
- Do not over mash the potatoes as this can cause them to become stiff and gluey.
- If your potatoes are too stiff, mix in a little extra milk.
- Taste before serving and season more if needed.
