A passover meal wouldn't be complete without haroseth, a traditional, chutney-like condiment.

The technique: Eggs change everything: The yolks add richness and texture, and folding in beaten egg whites elevates the sweet potato casserole to new heights.
The payoff: A sophisticated take on the classic marshmallow-topped sweet potato casserole.

The technique: Parboil sliced potatoes in whipping cream, then layer them with mushrooms and top with Gruyère.
The payoff: Great texture and flavor through and through—the cheese gets browned and toasty in the oven, and the layers of creamy potatoes and mushrooms are rich and satisfying.

The technique: High heat equals great flavor—roasting the new potatoes browns and crisps the skin, providing a little bit of crunch.
The payoff: Hearty potato taste and texture with only 25 minutes of prep.

The technique: It's ridiculously simple: Cut the potatoes into wedges, toss with olive oil and ground cumin, then roast.
The payoff: The ideal ratio of crisp to creamy, since there's more surface area exposed in the oven when the sweet potatoes are cut into wedges.

The technique: The perfect mashed potatoes aren't actually mashed. The key is using a potato ricer (which looks like a giant garlic press). This gadget gently breaks the potatoes into tiny, flaky pieces (rather than smashing them into a gluey mass), creating just the right texture.
The payoff: Light, fluffy, perfect potatoes. For horseradish mashed potatoes, replace the butter with five tablespoons olive oil (do not use extra-virgin), and mix in two tablespoons cream-style horseradish before seasoning the potatoes with salt and pepper.

This addictive appetizer is a delicious combination of sour cream, cheese, and corn. A little minced jalapeño adds heat.

A crème fraîche custard is folded into the mixed-fruit filling of this elegant nectarine-blackberry crisp.

This salty, savory nibble is perfect with the sparkling cocktail. A garnish of crispy shallots adds just the right amount of crunch.

Grilling the pizza dough adds a smoky flavor to the crust.

The beans need to soak overnight, so be sure to start this recipe one day ahead.

French pastry chefs dedicated this classic dessert to the Russian royal family. In this version, Grand Marnier-soaked berries are served with a tangy homemade ice cream (in place of the usual whipped cream). If you'd like, serve some sweet, crisp cookies alongside.
