Mashed Potatoes:
Bring a large pot of water to a boil. Add in potatoes and cook until tender, about 20-25 minutes.
While potatoes are cooking, melt butter in a medium saucepan over medium-low heat. Continue cooking butter until browned, stirring frequently, about 20 minutes.
Once potatoes are tender, place them in potato ricer, working in batches. Rice the potatoes into a large mixing bowl. You can rice them twice for extra creamy potatoes.
Once butter is browned, strain it with a fine mesh strainer into the mixing bowl. Add in half and half (a little at a time, you might not need all of it) and salt and pepper. Using a hand mixer or stand mixer, mix on medium-low speed until fluffy, about 5 minutes.
