Notes
You can halve or double this recipe easily. Warm the milk first for best results. You can use could milk but it will cool down the potatoes as well as make the potatoes less fluffy. Its a scientific process that I can't remember how to explain. :) You can substitute half & half for the milk for a creamier taste.The most important step for no lumps, is to mix them well before adding any milk. The most important step for fluffy potatoes is to thoroughly drain the potatoes so no water remains. You can add a few cloves of fresh garlic to boil with the potatoes for garlic mashed potatoes. You can add any other seasonings you like, chives, pepper, etc.
