Fill a large pot about 3/4 full of water and turn on high heat.
Wash and the peel potatoes.
Cut peeled potatoes into evenly sized cubes.
Once the water is simmering, add the potatoes. Boil for 15-20 minutes until fork-tender.
Drain potatoes and put back into pot. Immediately add salt and 3/4 stick butter so it starts to melt.
Beat while slowly adding half the can of evaporated milk.
Pepper to taste and beat until creamy. Add more butter and/or evaporated milk until you reach desired creaminess.
Don’t wait until the water is boiling to add the potatoes. Turn on the water while you are peeling the potatoes and add them to the pot as you cut them.
