Peel, wash, and cut the potatoes into large cubes. Cover with water and cook over high heat until the water comes to a boil. Reduce the heat to low, cover, and simmer for 30 minutes.
Crush the garlic cloves using a mortar and pestle, and juice the lemons.
To make the dressing, combine the crushed garlic, salt, lemon juice, olive oil, and dried mint. Whisk well until thoroughly combined.
Drain the liquid and mash the potatoes using a potato masher or hand mill. Please avoid using a blender.
Add the dressing, mix well to combine everything, then take a bite and adjust the salt to your taste.
To create uniform balls of mashed potatoes, use an ice-cream scoop to portion them elegantly onto a serving plate. Decorate with cherry tomatoes—optional, but recommended. Alternatively, spread the mashed potatoes on a flat plate like a dip. Heavenly!
