I prefer to leave the skins on my mashed potatoes, but if you prefer to remove the skins, you can peel them off using a knife and fork. Mash thoroughly using a potato masher or hand mixer. Add 1/3 c Roasted Garlic Infused Olive Oil, 4 Tbsp of butter (cut into pieces), and 1/3 c of warm milk. Stir until everything is well mixed into the potatoes. Season to taste with salt and black pepper.
