Why the Method Works
Potatoes cooked under pressure absorb less water than potatoes boiled in a pan, and a drier potato makes a creamier mash.
Peel them and cut into even chunks of 4 cm, which cook through in 8 minutes. Floury potatoes, such as Maris Piper or russet, give a light mash; waxy ones turn gluey when mashed.
The pot needs only 250 ml of water in the base, with a trivet or steamer basket if you have one. Drain them well and let them steam dry for 2 minutes in the open pot. The wet surface is what makes mash sloppy.
Heat the milk with the butter before it goes in. Cold milk cools the potatoes and gives a lumpy, sticky mash. Mash with a masher, not a food processor, which turns the starch to glue. Salt well; potatoes take more than you expect. Because the potatoes cook in steam they hold less water than boiled ones, so they take plenty of butter and milk without turning loose.
