Harrison’s Brown Butter Mashed Potatoes

Having a son who’s following in your footsteps is one thing. Watching him take what you’ve taught him and elevate it to something even better—that’s special. During his Christmas break from the Culinary Institute of America, Hyde Park, New York, a few years ago, he nudged me out of the way and made these mashed potatoes. I was skeptical, of course as I’ve been making mashed potatoes for decades. But there was no question his version was better. There’s a lot of pride in seeing him excel in the kitchen, making something as simple as mashed potatoes taste extraordinary. This recipe has become a new tradition in our family. Watching him cook now, with all that skill and precision, is a proud moment for me every time. This is his recipe, and I’ve adopted it as my own.

Ingredients

4 pounds Yukon Gold potatoes, peeled and cut into 1 1/2-inch pieces
3 sticks salted butter, divided
1 cup heavy whipping cream
2 long sprigs fresh thyme, crushed in your hand to release the oils
1 teaspoon fresh garlic, minced
1 tablespoon kosher salt, divided
2 teaspoons fresh ground black pepper

Instructions

This recipe is part of Robert St. John’s Mississippi Christmas and is available for purchase here.

Serves 6 to 8

Place the prepared potatoes in an eight-quart saucepot and cover with cold water, ensuring the potatoes are submerged by two inches. Add two tablespoons of kosher salt to the water.

Place the pot over high heat and bring to a simmer. Reduce heat to maintain a gentle simmer and cook until the potatoes are fork-tender, about 20 to 25 minutes.

Drain the potatoes thoroughly and spread them out on a baking sheet. Place the baking sheet in a low oven (200°F) for five minutes to allow the potatoes to dry out slightly. This helps intensify the flavor and ensures a smoother texture.

While the potatoes are drying, prepare the brown butter. In a medium skillet, melt 1 1/2 sticks of butter over medium heat, swirling the pan frequently. Once the butter foams and turns a rich, golden brown, immediately remove from the heat and set aside.

In a small saucepan, heat the heavy cream, thyme, and garlic until just simmering. Remove from the heat and allow the mixture to steep for ten minutes. Strain and keep warm.

Pass the dried potatoes through a food mill or ricer back into the pot. Place the pot over low heat, stirring constantly to keep the potatoes warm.

Slowly fold the brown butter into the potatoes, allowing them to absorb the fat completely. Gradually add the warm infused cream, mixing until silky and smooth.

Fold in the remaining 1 1/2 sticks of cold, diced butter, a few pieces at a time, which creates a smooth texture and a glossy finish.

Season with the remaining salt and fresh ground black pepper. Taste and adjust seasoning if needed.

Serve immediately or keep warm using a bain-marie (water bath) to maintain texture.

A Quiche for David

Quiche is French in origin, so this recipe is probably an abomination to some. My friend David Trigiani is a dual-citizen Italian is always taking a stand in the French food versus Italian food debate. Heavy whipping cream is a must, and never buy pre-shredded mozzarella. Grate your own. The same goes for parmesan cheese. Never, I repeat never buy that powdery substance in the green can. Invest in a good grater and you'll be a better cook for it. David lives in Jackson, Mississippi, but spends most of his holidays in Italy. He’s an excellent cook, though I have never eaten quiche in his home. Maybe this will inspire him, and I’ll get an invitation.

Orange Crepes with Sugared Cranberries

I prefer fruit over chocolate after a meal. Orange and cranberries are a perfect pairing, especially during the holidays. This is an excellent and easy dessert after a heavy meal. These can be served individually on small plates or in a casserole for a buffet.

Grilled Tripletail with Lump Crab and Chive Beurre Blanc

Tripletail has always been my favorite Gulf fish. The old-timers used to say, "If you can see a tripletail, you can catch a tripletail." They have this peculiar habit of floating near the surface around buoys, crab traps, and other floating objects, often lying on their sides and appearing almost lifeless. This behavior makes them easy to spot and, if you're quick with your cast, easy to hook. The meat is mild, white, and flaky—perfect for grilling. Pairing it with lump crab and a chive beurre blanc elevates this dish to something truly special.
