Instructions
Put the potatoes and whole garlic cloves into a large pot and cover with 1-inch of cold water. Bring the pot to a boil over high heat then reduce the heat, cover the pot, and simmer for 15 minutes, until the potatoes are tender. Reserve 1 cup of the cooking liquid and then drain the water from the pot.
5 lb russet potatoes, 6 cloves garlic
Add the butter to the pot and give it a few minutes to melt. Add the sour cream, cream, butter, and salt and mash the potatoes with a potato masher until smooth. Thin the potatoes with a little of the reserved cooking liquid. You want the potatoes to be slightly thinner than normal.
1 cup sour cream, ½ cup cream, ¼ cup butter, 2 teapoons sea salt
Transfer the potatoes to a buttered casserole dish and cover it with aluminum foil. Let the potatoes cool before moving the casserole dish to your fridge. Can be made to this step up to 3 days in advance.
Put the mashed potatoes into your oven when it's cold - see notes. Turn your oven to 350 degrees Fahrenheit. Once it reaches temperature, set a timer for 45 minutes. Then, remove the foil and continue to bake for another 15 minutes, until it is bubbling and hot. If you want the potatoes a little extra browned, broil them for a few minutes. Serve topped with minced chives.

Notes
Putting a cold glass or ceramic casserole dish into a hot oven can cause it to crack. To avoid this, we heat the oven with the cold casserole dish in it. If your oven is hot (say, from cooking a turkey) make sure to let the mashed potatoes sit on your counter for at least half an hour before you put them into the oven. If you'd prefer, you can also reheat these potatoes in a microwave.
