Instructions

Begin by filling a medium pot with 8 cups of tap temperature water and 1½ teaspoons of kosher salt. Next, peel, rinse, and cut the potatoes into roughly the same-sized large pieces. They shouldn't be smaller than 2-inch (5cm) cubes. (see FAQs about how potato piece sizes affect texture/flavor).
Add them to the pot and bring the pot to a very gentle boil on your stovetop. You should see foam build up on the top of the water, but the water's surface shouldn't look like it's doing more than shifting a little. It’s okay to allow some bubbles while boiling but keep them gentle. You don’t want the potatoes moving around too much in the water or they will rub against each other and break apart before the centers can cook all the way through. Boil for between 30-45 minutes, until a fork slides into the center of the largest piece(s) without resistance (See FAQ for a more thorough description of doneness)
About 5 minutes or so before the potatoes are done, add the butter and Brown Butter Powder to a small sauce pot or sauce pan on the stove top. Cook them at medium-high heat, just until the butter begins to froth and the powder is fully imbued by the butter. Turn off the heat and set the boosted brown butter aside.
Drain the pot of potatoes over a colander. Give the potatoes 1-2 minutes to let off some steam. Then, using tongs to transfer the hot pieces of potato, push everything through a potato ricer back into the empty pot. Return the pot to the stovetop and turn the burner on warm/low. Let the potatoes sit for another 3-5 minutes to allow them to steam and dry out even more. To help release moisture, use a fork to gently fluff the potatoes every minute or so.
At this point, pour just the bosted brown butter over the riced potatoes. (Why just butter? See the FAQs!) Use a spatula to fully scrape out the pot or pan of butter and gently fold the potatoes around until the butter is completely incorporated. The potatoes will smooth out and the butter will give them a golden tint. Then, add the rest of the salt, the pepper, and the sour cream. Fold again, being careful not to smoosh the potatoes, until the sour cream is mostly incorporated and then, again, gently mix in the milk, to thin everything out. Taste your homestyle brown butter mashed potatoes and add any additional salt, if needed.

Notes

Leftover potatoes can be stored for up to 4 days in the refrigerator.
This recipe makes about 3.5-4 cups of mashed potatoes and will serve up to 8 people. Most people will eat about 1/2 cup (120 ml by volume) of mashed potatoes with a meal. So, consider this at your next holiday party or Sunday dinner.
Here's a quick breakdown on potato sizes from typical 5lb (2.3kg) grocery store bulk bags: small potato .22lbs (98 gm); medium potato .35 lb (165 gm); large potato .4 lb (175 gm). This does NOT count towards membership bulk warehouses, like Costco. Those potatoes are bigger than my face!
If you don't already have Brown Butter Powder, you can make it at home (though I'm working on online sales. Soon you'll be able to buy it! YAY!). If you don't already have some, add about 30-45 minutes into making a batch of toasted milk powder at home and keep it for other things!
