The potato is a venerable tuber. Its history, at least as defined by its cultivation by people, dates back at least 7,000 years. Its origin can be traced to the Andes Mountains in South America, somewhere around northwestern Bolivia and southeastern Peru. Indigenous cultures discovered that the tuber, which grew in different varieties, could be boiled and mashed to produce a tasty, and relatively healthy, foodstuff.
Centuries later, people around the world are boiling, frying, steaming, and stewing the thousands of different varieties of potatoes. (As an aside, there are approximately 4,000 different varieties of potatoes in the Andes Mountains alone.) This is due partly to the fact that potatoes can be cultivated in a wide range of environs, from the coasts to the mountains. They can also be grown in a wide range of places, from Peru to Greenland. Most importantly, potatoes are relatively cheap to cultivate and more productive than other crops (like grains), making the tubers an important food for the masses.
Someday, I will explore the role of the modest potato in cucina povera, because that subject, as well as that cuisine, interests me greatly. However, I had a more immediate problem: how to best prepare mashed potatoes for a recent holiday feast. For decades, I did prepared mashed potatoes the "traditional way," boiling the potatoes, and mashing them while adding butter and milk. That was how I was taught to prepare them. A while back, I used to experiment by adding cheese, such as Parmigiano Reggiano or Wesleydale cheese, or other ingredients, like bone marrow (which is a popular post among readers). These efforts produced good side dishes, but I wanted to improve on my mashed potatoes skills.
Enter Chris Kimball's Milk Street. I had gotten a subscription to the magazine as a gift from my inlaws. One of the magazines had a recipe for butter braised mashed potatoes. The use of the word "braised" caught my attention because it suggested a different way to make the dish. I read the recipe and decided to give it a try. Milk Street's recipe draws its inspiration from a potato dish found in Turkish cuisine. (Although Milk Street does not name the recipe, perhaps it was Patates Pacasi, which Milk Street highlighted back in 2022.) The cooks at Milk Street modified the Turkish recipe by reducing the water and adding the butter. This step was based on science, as the butterfat coats the potatoes, reducing water absorption and helping to preserve the potato flavor. It also reduces the amount of starch granules that burst, which results in a fluffier and less gluey texture.
The recipe suggests using russet potatoes over Yukon Gold. Russet potatoes have higher starch contents, as well as lower water contents, which help produce lighter, fluffier mashed potatoes. By contrast, Yukon Gold potatoes will produce a creamier mashed potato, which is not quite the result contemplated by the recipe. Light, fluffy potatoes are the goal; so, I used russet potatoes. The end result was far better than any mashed potatoes that I have previously prepared. They were truly lighter and fluffier, while still buttery and potatoey in flavor. These butter-braised mashed potatoes were also a hit among the guests. It was the one dish that had the least amount of leftovers.
I think I have found my go to recipe for mashed potatoes. Thank you, Milk Street.
BUTTER-BRAISED MASHED POTATOES
Recipe from Christopher Kimball's Milk Street (Oct.-Dec. 2025), pp. 12-13
Serves 6-8
Ingredients:
- 3 pounds russet potatoes, peeled and cut into 1-inch chuncks
- 18 tablespoons salted butter, cut into chunks
- Kosher salt
- Ground black pepper
- Boiling water, if served right away
- Chives, chopped, to serve
Directions:
1. Prepare the potatoes. Place the potatoes in a colander; rinse briefly under cool water while tossing. Drain well, then transfer to a large (7-8 quart) Dutch oven, distribute evenly. Add 1 1/2 cups of water; the potatoes will not be fully submerged. Sprinkler with 1 1/2 teaspoons salt, then drop in the butter.
2. Boil the potatoes. Bring to a boil over medium high heat, then cover, reduce to medium low heat and simmer, stirring occasionally until the potatoes fall apart when pierced with a fork, 25-30 minutes. Uncover and cook over medium stirring only once or twice, until only a little starchy liquid remains in the bottom of the pot, about 3 to 5 minutes. Off heat, use a potato masher to mash the potatoes until smooth.
3. If serving right away. Add 1/2 cup boiling water and mash until the water is incorporated. Taste and season with salt and pepper. Transfer to a warmed serving dish and sprinkle with chives and additional pepper.
4. If making ahead. Transfer to a container and cool completely, then cover tightly and refrigerate up to 2 days. To reheat, transfer the potatoes to a large saucepan and add 3/4 cup water. Cover and cook over medium-low, mashing occasionally (do not stir) until the potatoes are warm and fluffy, about 20 minutes; add more water a few tablesppons at a time as needed to adjust consistency. Taste and season with salt and pepper. Transfer ot a warmed serving dish and sprinkler with chives and additional pepper.
PEACE.
