Slice your potatoes in half.

Scrape the flesh out and put it into a bowl. Put the skins on a baking sheet.

Mash the potatoes with a potato masher.

Stir in sour cream, horseradish, chives, salt, and pepper. Give a good taste and make sure that there is enough seasoning.

Put the mashed potatoes back into the potato skins.

Cover with shredded cheese.

Bake in a 375 degree oven for 20 to 30 minutes. The cheese should be melted and gooey and hot all the way through.
