The one I posted, at the link, is in a thread desertjean asked about potatoes cooked in milk.
I've done both the grilled (first recipe) and ungrilled (second recipe) versions.
Warm Grilled Potato Salad
8 medium-sized Yukon gold potatoes
2 cups heavy cream
2 cups whole milk
4 cloves garlic, peeled and gently smashed
4 sprigs fresh thyme
1 bay leaf
kosher salt & freshly ground black pepper
extra-virgin olive oil
1 tablespoon whole grain mustard
2 scallions, for garnish
ice water
Add potatoes, cream, milk, garlic, thyme and bay leaf into a large sauce pan and gently boil for 15 minutes until potatoes are just tender and the tip of a pairing knife goes through with little resistance. Allow to cool in the cream mixture. Once cooled, strain potatoes and lay out in a single layer on a kitchen towel to drain. Cut the potatoes into large pieces then brown on a hot grill with a little olive oil for 4-5 minutes until they just get a little golden color. Place browned potatoes in a mixing bowl. Gently smash with a potato masher or large metal spoon. You want to smash the potatoes so they are broken up but there is still a lot of texture. Strain the cream mixture and add just enough to make the potato base creamy (about 1-1/2 cups). Add 1 large tablespoon of whole grain mustard and season with plenty of kosher salt and freshly ground black pepper. Garnish with curled scallion threads. Make these by cutting scallions on the bias into thin ribbons and soak in ice water until they curl up, about two minutes (Pat’s note: I didn’t soak in ice water, just sliced and garnished.) Serves 4-6.

Grainy Mustard Mashed Potatoes
8 medium-sized Yukon gold potatoes, quartered, unpeeled
2 cups heavy cream
2 cups whole milk
4 cloves garlic, peeled and gently smashed
4 sprigs fresh thyme
1 bay leaf
Extra-virgin olive oil
2 tablespoons butter
1 tablespoon whole-grain mustard
Kosher salt and freshly ground black pepper
Add potatoes, cream, milk, garlic, thyme and bay leaf into a large saucepan and gently boil for 15 minutes until potatoes are just tender and the tip of a paring knife goes through with little resistance. Strain potatoes and reserve the cream mixture but discard the bay leaf, thyme stems and the garlic. Mash the potatoes and fold in the cream mixture until the potatoes are smooth and creamy. Fold in about a tablespoon of the olive oil, the butter, and the whole-grain mustard. Season with salt and pepper.

Pat’s notes: I did this version for a couple Thanksgiving dinners and they turned out well. Asked Charlie if I could do them slightly ahead and how to hold them. He said: “you can put them in a 200 degree oven in a buttered pan with a buttered piece of parchment on top. OR put the pan in a bain marie.”.
