1. Peel and quarter 1.8kg cream-delight potatoes. Place in a large pot, cover with 10cm of cold water and bring to the boil.
2. Add 1 tsp sea salt and simmer potatoes until tender, about 15 minutes. Reserve 1 cup of cooking liquid and drain potatoes in colander.
Return potatoes to pot with 1 cup warm low-fat milk, 1/4 cup unsalted butter and 1/2 cup reserved liquid. Mash with potato masher until almost smooth, adding more cooking liquid as needed.
Season to taste with sea salt and pepper.
