Cut your potatoes into the same sized pieces to ensure they all cook evenly and at the same time.
Boil potatoes in salted water until JUST fork-tender. Try not to overcook too much as they can become quite sticky or gluey when overcooked.
Drain cooked potatoes, then add in the hot milk, butter, salt, pepper and a garlic.
Mash the potatoes with a potato masher until smooth, adding a little extra milk if needed. Then you could also use an electric-hand-mixer to ensure a smoother consistency. I Do! Beat just enough for them to smooth out while being extra careful not to over beat as they may become gooey.
