- Place the potatoes and garlic in a pot. Cover with cold water. Season with salt. Bring to a boil and simmer for 25 minutes or until the potatoes are tender and fall apart easily when pierced with a fork. Drain. Return to the pot.
- Using a potato masher, purée the potatoes and garlic with the butter. Gradually add the milk and mix until smooth (see note). Season with salt and pepper.
- Serve in individual bowls. When ready to serve, add a drizzle of browned butter or a cube of butter, if desired.
If you choose to prepare the mashed potatoes in advance, add a little extra milk to make the mashed potatoes slightly runnier than you normally would. Mashed potatoes tend to thicken up very quickly when not used immediately.
