Rinse the potatoes and place, unpeeled, in a saucepan. Cover with water, add salt and allow to simmer for 20-30 minutes until soft. Drain, cool under running water and peel.
Meanwhile, crush the garlic with salt in a pestle and mortar, until it becomes a paste.
Mash the potatoes, either with a fork or a masher (never in a blender), adding the olive oil until well blended. Add the lemon juice, vinegar and garlic paste a little at a time. Finally, mix in the milk until it becomes a smooth paste, and season with salt to taste
