Ingredients for Ultra-creamy mashed potatoes
1,800 g medium yukon gold potatoes, scrubbed
20 ml kosher salt, plus more
360 ml full-fat milk
120 ml double cream
1 head garlic, halved crosswise
3 sprigs rosemary
225 g unsalted butter, room temperature, cut into pieces
freshly ground black pepper
a potato ricer or food mill fitted with fine disk
How to make Ultra-creamy mashed potatoes
Place the potatoes in a large pot and cover them with cold water by approximately 2.5 cm.
Add a large handful of salt, ensuring the water tastes briny, like the sea, and bring to a boil.
Reduce the heat and simmer the potatoes for 30–35 minutes, or until they are very tender but not crumbly.
Drain the potatoes and briefly rinse them with cool water to remove any excess starch. Return the potatoes to the warm pot (off heat) to dry while you prepare the milk mixture.
Warm the milk, single cream, garlic, and rosemary sprigs in a small saucepan over medium heat for about 5 minutes, or until fragrant. Remove the pan from the heat.
Pass the hot potatoes through a ricer or food mill into a large bowl (cold potatoes will become gummy).
Add the butter and 4 teaspoons of salt to the potatoes, stirring until the butter is completely incorporated.
Strain the warm milk mixture through a fine-mesh sieve into a large measuring jug. Pour the strained mixture into the potatoes, 120 ml at a time, stirring after each addition until fully incorporated and the mixture is smooth before adding more.
Serve the mashed potatoes topped with a few grinds of pepper.
If preparing in advance, the mashed potatoes can be made up to 1 day ahead. Cover and chill in the fridge. To reheat, warm over medium heat, stirring often, and add 60 ml of milk or stock to thin out if needed.
