potatoes (as many as you like)
milk (2 tbsp. for each potato)
grated Cheddar cheese (3 tbsp. for each potato)
salt and pepper (Pinch of each)
bowl
hand beater or potato masher
baking pan

Bake your potato. Preheat your oven to 400 degrees. Wash the potato well. Prick some holes in it with a fork and rub it all over with a little oil. Then place it right on the oven rack (no pan) and bake 45 to 60 minutes. You can tell when it's done with an oven mitt. When it is squeezable, its done.

Take the potato out of oven; wait a little bit to cool, then cut in half and scoop the potato out into a bowl. Keep one of the skins. Save 1/3 of the cheese to sprinkle on top of the potato before it goes in oven. Mix the rest of the cheese, the milk, and the salt and pepper with the potato. If you like butter, add a pat per potato. Now use the masher or miser but do it when the potato is still warm. Put your potato and cheese mixture back into the potato skin you saved (it won't really fit but that ok). Put it in a baking pan; sprinkle the rest of the cheese on top of it and put back into the oven for 20 minutes at 350 degrees.

It's done when it starts to melt.
