Crispy Potato, Artichoke, Leek, and Gruyère Tart

Prepare a medium-hot fire (425°F) in a wood-fired oven or cooker.

Cut the leeks crosswise into half rings and rinse well. Heat 3 tablespoons of the olive oil in a terra-cotta baker, in the oven or cooker, and cook the leeks until translucent, about 7 minutes. Transfer to a bowl and set aside.

Remove the outer artichoke leaves, then thinly slice the artichokes lengthwise. Add the lemon juice to a bowl of ice water and place the artichoke slices in the water. Drain and pat dry the artichokes dry with paper towels. In the same clay baker, sauté the sliced artichokes in the olive oil left over from the leaks over medium-high heat in the oven or cooker until lightly browned, about 5 minutes. Add the wine and stir to scrape up the browned bits from the bottom of the pan. Add the thyme and salt and pepper to taste and cook for 3 minutes, or until the moisture is removed. Remove from the heat and set aside.
