1 lb / 450 g celeriac, peeled and 1-inch diced 1 lb / 450 g Yukon Gold potatoes, peeled and 1-inch diced 3 tbsp unsalted butter 1/2 cup (120 ml) whole milk, warmed (plus more as needed) 1 tbsp extra-virgin olive oil 1 tsp finely grated lemon zest 1–2 tsp fresh lemon juice, to taste 1 tsp fresh thyme leaves, finely chopped 2 tbsp fresh chives, finely snipped (optional) Kosher salt, to taste Freshly ground black or white pepper, to taste
1. Place celeriac and potatoes in a pot, cover with cold, well-salted water by 1 inch, and bring to a boil. Reduce to a brisk simmer and cook until very tender, 15–20 minutes. 2. Drain thoroughly, return to the hot pot, and let sit 1–2 minutes to steam off excess moisture. 3. Mash with a potato masher or pass through a ricer for a silkier texture. 4. In a small saucepan, melt the butter in the warm milk; stir in the olive oil. Gradually fold into the mash until creamy and supple, adding a splash more milk if needed. 5. Season with lemon zest, 1 teaspoon lemon juice to start, thyme, salt, and pepper. Taste and adjust salt, pepper, and lemon juice until bright but balanced. 6. Fold in chives (if using) and serve hot.
