Ingredients:
- 3 lbs Russet or Yukon Gold potatoes
- 1 tbsp fine sea salt
- 0.5 cup unsalted butter, cubed
- 0.5 cup heavy cream
- 0.25 cup sour cream
- 2 cloves garlic, smashed
- 0.5 tsp salt
- 0.25 tsp white pepper
Instructions:
- Peel 3 lbs potatoes and cut into uniform 1 inch cubes.
- Place cubes in a pot, cover with cold water by an inch, and add 1 tbsp fine sea salt.
- Bring to a boil, then reduce to a simmer for 15 minutes until a fork slides in with zero resistance.
- While potatoes boil, combine 0.5 cup heavy cream, 0.25 cup sour cream, and 2 smashed garlic cloves in a small pan over low heat.
- Pour the potatoes into a colander and let the water run off completely.
- Return the empty pot to the warm burner and toss the drained potatoes back in for 1 minute until the surface of the potatoes looks dry and chalky.
- Press the hot potatoes through a ricer or use a hand masher.
- Remove the garlic cloves from the warm cream and gradually stir the liquid and 0.5 cup cubed butter into the potatoes.
- Add 0.5 tsp salt and 0.25 tsp white pepper, folding gently until the butter has completely vanished into velvety ribbons.
- Taste and add a pinch more salt if needed, then serve immediately.
