Finally, at AllRecipes.com, I find a recipe for home fries that doesn't expect you to have cooked potatoes laying around!!
3 medium russet potatoes, cubed
3 T butter
Salt & pepper to taste
Rinse potato cubes with cold water, and drain well. Melt butter in a large skillet over medium heat. Place potatoes in the skillet, and stir to coat with butter. Season with salt and pepper. Cover with a lid, and cook for 10 minutes. Remove the lid, and cook for another 10 minutes, turning frequently until brown and crisp on all sides.
