Simple Cooking

Baked tarts can be frozen up to 3 weeks. Without thawing, reheat them in a 350°F oven for about 10 minutes. Instead of large tarts, you can make individual-size tartlets: Cut the pastry into eight 4-inch squares; bake for about 20 minutes.

The olives can be prepared three days ahead and refrigerated, covered. Bring to room temperature before serving.

Using tequila as a steaming liquid enhances the flavor of the clams and oysters, but it’s fine to use water instead. Setting the skillet over a grill gives the dish a touch of smokiness, or you can use your stove turned to medium-high heat.

Ciabatta, a long, flat Italian bread, is ideal for this recipe, but you could also use a rustic round loaf; instead of splitting it horizontally, cut 6 1 1/4-inch-thick slices. You can refrigerate leftover chimichurri in an airtight container for up to 2 days.

If you can’t find lemon thyme, use small, fresh basil leaves instead.

If using prepared horseradish, reduce the amount of lemon juice to 1 tablespoon.
