This recipe requires the potatoes to be baked first. I do this in the microwave as it is quick and easy. Refer to the manufacturer guidelines. You want the potatoes nice and soft. Once done cut in half and allow to cool slightly, unless you have asbestos hands. I use a Mouli legume or you could use a potato ricer. This ensures there are no lumps. You then need to use your sense of taste to perfect this. Add salt to taste, a hunk of butter and a splash of milk. Add in small amounts as it is easy to add but impossible to take away. What you will get is a mash that has an intense potato taste. You may need to keep heating in a pan on a very low heat as the butter and milk will reduce the temperature when added.
