Dulce de Leche Cheesecake Squares

Ingredients:

Crust:
3 1/2 ounces wheatmeal crackers (sometimes called digestive biscuits), crumbled (1cup)
2 tablespoons sugar
Pinch salt
3 tablespoons unsalted butter, melted

Filling:
1 teaspoon unflavored gelatin (from a 1/4-ounce envelope)
1/4 cup whole milk
8 ounces cream cheese, softened
2 large eggs
3/8 teaspoon salt
1 cup dulce de leche (12 1/2 ounces)

Glaze:
3 ounces fine-quality bittersweet chocolate (not unsweetened), coarsely chopped
1/2 stick (1/4 cup) unsalted butter, cut into pieces
2 teaspoons light corn syrup

Preparation:

To make the crust: Put oven rack in middle position and preheat oven to 325 degrees F. Line bottom and sides of an 8-inch square baking pan with 2 sheets of foil (crisscrossed), leaving a 2-inch overhang on all sides.
Finely grind crackers with sugar and a pinch of salt in a food processor. With motor running, add butter, blending until combined. Press mixture evenly onto bottom of baking pan. Bake 10 minutes, then cool in pan on a rack 5 minutes.

To make the filling: Sprinkle gelatin over milk in a small bowl and let stand 2 minutes to soften.

Beat together cream cheese, eggs, salt, and gelatin mixture in a bowl with an electric mixer at medium speed until well combined, about 2 minutes, then stir in the dulce de leche gently but thoroughly. Pour filling over crust, smoothing top, then bake in a hot water bath in oven until center is just set, about 45 minutes. Cool cheesecake completely in pan on rack, about 2 hours. Chill, covered, at least 6 hours.

Glaze cake within 2 hours of serving. Heat all glaze ingredients in a double boiler or a small metal bowl set over a saucepan of barely simmering water, stirring until smooth, then pour over cheesecake, tilting baking pan to coat top evenly. Chill, uncovered, 30 minutes.

Lift cheesecake from pan using foil overhang and cut into 1-inch squares with a thin knife, wiping off knife after each cut.

Chocolate Lime Cheesecake

Ingredients:
7 ounces chocolate wafer cookies
1/3 cup unsalted butter, melted
1 1/2 pound cream cheese (recommended: Philadelphia)
1 cup sugar
4 whole eggs
2 egg yolks
4 limes, juiced or 3/4 cup
Special equipment: spring form pan

Preparation:
Preheat oven to 350 degrees F.

Place a large overlapping piece of aluminum foil over the bottom of the springform pan, and then insert pan ring over it. Fold the foil extra foil up and around the pan and place the whole thing on a second piece of foil, also folding it and pressing it securely around the pan, having a water tight covering.

In a food processor, process cookies until they are crumb-like, add melted butter and continue to process. Pour crumb mixture into springform pan and press with your fingers to line the pan. Place the pan in the refrigerator to set while you prepare the cheesecake.

Place a kettle of water on for water bath. In a food processor beat the cream cheese until smooth, add the sugar, eggs, egg yolks, and lime juice.

Take crumbed pan from the refrigerator and place it in a roasting pan. Pour the cheesecake mixture into the crumb pan, and then carefully pour the hot kettle of water into the roasting pan so the water reaches 1/2 way up the pan so the water does not splash into cheese cake.

Place roasting pan in oven for 1 hour, checking after 50 minutes. It should feel set, but still wobbly in the center. Take the roasting pan out of the oven, carefully remove the springform pan from the roasting pan and place it on a rack. Peel off the outer layer of foil, and tear away the side bits of the first layer of foil and leave the pan to cool. Once the cake comes to room temperature, place it in the refrigerator for 20 minutes before serving. Transfer to the plate you're going to serve it on, a plate without a lip, or a cake stand. Unclip the springform pan and remove the outer part. Carfully lift the cheesecake removing the metal bottom. The aluminum foil can stay on the cake. Serve chilled.
