First of all, this is one of those recipes with no actually recipe involved because really it's all about taste.
Potatoes-skinned and boiled ( I prefer white)
Mild chedder- shredded
Milk (more fat the better)
Real butter (A lot)
While potatoes are boiling fry bacon in a pan and set aside to cool and dry (I like to let it cool and dry so it gets more crispy). After potatoes are soft drain, put back in pan and set on low heat for about 1 minute to boil out all water. Add in about 1/4 cup milk and half stick butter, 2 tbsp salt and some cracked pepper. Use a potato masher (I prefer a masher for this dish because I like a few lumps) and mash it all together. Put in a bowl while steaming hot and top with tons of fresh shredded cheddar cheese. Allow cheese to melt then top with sour cream (a big heaping spoonful) and a handful of crispy crumbled bacon.
