Leaving the skin on, cut potatoes in half and add to a pot of water. Boil potatoes until you can stick a fork in them and it slides off. Drain water and return potatoes to pot.
Mash potatoes until there are no more clumps. You can use a potato ricer, stand mixer, electric hand mixer, or potato masher. Whatever works for you.
In a small pot add heavy cream, butter, thyme sprigs, bay leaf, whole garlic cloves, nutmeg, salt, and pepper. Simmer on low heat for 5 – 10 minutes.
Using a strainer, strain the cream mixture over your potatoes. Use a fork to mash the garlic cloves through the strainer. Combine mixture well with potatoes.
