Key Lime Curd Recipes

Steps:

• Place the sugar, butter, lime juice, lime zest in the top of a double boiler; stir over medium-high heat until butter melts. Mix 2 tablespoons hot lime mixture into the eggs and stir to blend.
• Reduce heat to medium until water simmers. Slowly whisk egg mixture into the lime mixture. Cook over the double boiler until lime mixture thickens and coats the back of a wooden spoon, 20 to 25 minutes. Cool slightly and spoon into a clean, glass jar. Cover and refrigerate.

Steps:

• Whisk the sugar, 1 tablespoon lime zest, the lime juice and salt in a medium saucepan. Whisk the whole eggs and yolks in a small bowl, then whisk into the lime mixture.
• Cook the mixture over medium heat, whisking constantly, until it¿s thick like pudding, 6 to 8 minutes. Remove from the heat and whisk in the butter a few pieces at a time until incorporated.
• Strain the mixture through a fine-mesh sieve into a small bowl, pushing it through with a rubber spatula. Press plastic wrap directly onto the surface to prevent a skin from forming; let cool to room temperature. Stir in the remaining 1 teaspoon lime zest. Cover and refrigerate until completely set, at least 4 hours and up to 5 days.

Steps:

• Combine sugar, eggs, lime zest, and juice in a medium nonreactive saucepan, and set over medium-low heat. Cook, whisking constantly, until mixture begins to thicken and holds the mark of the whisk, 10 to 12 minutes.
• Remove pan from heat, and whisk in butter, a piece at a time, until well combined. Strain mixture through a sieve into a glass bowl. Lay plastic directly on surface to prevent a skin from forming. Chill 3 hours or overnight to set the curd.

Steps:

• Preheat the oven to 350 degrees F.
• In the bowl of an electric mixer fitted with a paddle attachment, mix the butter and sugar together until they are just combined. Add the vanilla. In a medium bowl, sift together the flour and salt, then add them to the butter-and-sugar mixture. Mix on low speed until the dough starts to come together. Dump onto a surface dusted with flour and shape into a flat disk. Press the dough into a 10-inch-round or 9-inch-square false-bottom tart pan, making sure that the finished edge is flat. Chill until firm.
• Butter 1 side of a square of aluminum foil to fit inside the tart and place it, buttered side down, on the pastry. Fill with beans or rice. Bake for 20 minutes. Remove the foil and beans, prick the tart all over with the tines of a fork, and bake again for 20 to 25 minutes more, or until lightly browned. Allow to cool to room temperature.
• Remove the zest of 4 limes with a vegetable peeler or zester, being careful to avoid the white pith. Squeeze the limes to make 1/2 cup of juice and set the juice aside. Put the zest in a food processor fitted with a steel blade. Add the sugar and process for 2 to 3 minutes, until the zest is very finely minced. In the bowl of an electric mixer fitted with a paddle attachment, cream the butter with the sugar and lime zest. Add-- the eggs, 1 at a time, and then add the lime juice and salt. Mix until combined.
• Pour the mixture into a 2-quart saucepan and cook over low heat, stirring constantly, until thickened, about 10 minutes. The lime curd will thicken at about 175 degrees F, or just below a simmer. Remove from the heat and set aside.
• Fill the tart shell with warm lime curd and allow to set at room temperature. Once set, serve immediately or refrigerate until ready to serve.
