3 lbs. yams, scrubbed
Boiling water
Salt
1/4 tsp. ground white pepper
1/4 c. butter
3/4 c. milk
16 whole regular-sized marshmallows

1. In large saucepan or Dutch oven, cook yams in boiling water to cover, to which one teaspoon salt has been added. Boil, covered, about 25 to 30 minutes, until fork-tender; drain.

2. Peel yams, mash with fork on wooden board. Scoop into large bowl, add 1 teaspoon salt and the pepper.

3. Preheat oven to 350 degrees. Grease a 2 1/2 quart casserole. Heat butter with milk until rim of bubbles form around edge of pan. Slowly pour hot milk and butter into mashed yams, beating at low speed of electric mixer as you add. (Or use potato masher.) Continue beating at high speed until very smooth.

4. Spoon yam mixture into prepared casserole. Place marshmallows 1/2" into yam mixture, about 1" apart. Bake 35 to 40 minutes or until tops of marshmallows are golden brown. Makes 10 to 12 servings.
