Mustard Mashed Potatoes

5 red potatoes, scrubbed and halved

2 tablespoons butter

¼ cup milk

salt and pepper to taste

¼ cup whole grain mustard

Place the potatoes into a large pot and cover with salted water. Bring to a boil over high heat, then reduce heat to medium-low, cover, and simmer until tender, about 20 minutes. Drain and allow to steam dry for a minute or two. Mash potatoes in a large bowl with the butter and milk, and season with salt and pepper.

Whip the potatoes using an electric mixer set on medium until smooth, 3 to 4 minutes, adding more milk if the potatoes are too dry. Beat in the whole grain mustard, and serve immediately.
