Cheddar Cheese Mashed Potatoes

3 pounds russet potatoes
1/4 cup butter
2 cups sharp cheddar cheese, shredded
hot whole milk
salt

Peel potatoes and cut into even size pieces.
Add the potatoes to a large pot and cover so water comes about 2 inches above the potatoes.
Bring to a boil then add a generous amount of salt (about 2 tablespoons).
Boil until potatoes are tender and give no resistance when poked with a fork. (depending on the size of your potatoes about 20 minutes.)
Drain the potatoes, add butter and mash with a masher until there are no lumps. Add Cheddar and mix in. Add enough hot milk to get the desired consistency. Add salt if necessary.
