This Irish dish is best made with coarse skinned baking potatoes, because they break down easily to produce fluffier mashed potatoes.
Peel potatoes. Cut each into 3 chunks. In 12 cup casserole, sprinkle potatoes with 2 tbsp water, cover, and microwave on high for 15-18 minutes or until tender, rearranging occasionally. Mash well. Stir in milk, onions and butter. Microwave, uncovered on high for 1 minutes or until heated through. Add salt and pepper, beat until smooth. Makes 4 to 6 servings.
