How to Make It
Place the potatoes in a large saucepan with the garlic and enough lightly salted water to cover. (Can be done to this point up to 4 hours ahead. Cover and refrigerate.) Place over high heat and bring to a boil. Reduce heat to low, cover, and simmer 15 to 20 minutes or until fork-tender. Drain.
Beat with an electric mixer or mash with a potato masher until smooth. Add the butter. Gradually add the milk until the potatoes are fluffy. Blend in the salt and herbs.
To fake it...and save 30 minutes: Heat two 20-ounce packages red mashed potatoes according to the label directions. Beat in one 5.2-ounce package Boursin or another garlic-herb cheese. Total time: 10 minutes.
