About a pound of potatoes, cut into 1-inch chunks (I usually use 4 rinsed, unpeeled Yukons)
2 big pinches of salt
2 tablespoons of butter (about 1/2 tablespoon per potato)
1 tablespoon half & half (or cream or milk)
2 teaspoons mayo (optional)
Place the potatoes in a microwave safe bowl or dish, cover with plastic wrap, and make a half-inch slit in the top.
Microwave the potatoes for 9-12 minutes (depending on how many potatoes you have), until they can be easily pierced with a fork.
Remove them from the microwave and roughly mash them with a large fork, a big wooden spoon, or a potato masher to let any excess moisture evaporate.
Add your butter and mash until it’s melted, then add your half & half and mayo and mash again. Even if you are mayo-averse, I recommend it—it really helps with emulsification.
Give your ‘tates a taste, then season and garnish as you see fit.
