These potatoes have been a long time favorite when I make a typical meat and potatoes meal. My grandmother taught me to make this dish when I was little and I thought I had a great job being picked to peel the potatoes. The kitchen would get steamy as they boiled and I could just see the butter and cheese melting on them in my mind. Grandma always mashed them with a metal masher and I remember her wiping a stray lock of hair away from her face with the back of her hand. These days I cheat and use a mixer to get rid of the lumps. Somehow without the lumps they just aren't grandmas potatoes.
