Orange Marmalade Bars Recipes

Steps:

• For the crust: Preheat the oven to 350 degrees F. Grease a 9-by-13-inch pan with butter.
• Stir together the flour, granulated sugar and salt in a bowl. Add the butter to the bowl and use a pastry cutter to cut it all together until the mixture resembles fine crumbs. Press into the prepared pan and bake until golden around the edges, about 20 minutes.
• For the filling: Stir together the granulated sugar and flour in a bowl. Crack in the eggs and whisk to combine. Add the orange zest and juice and mix until combined. Pour over the crust and bake until the filling is set, about 20 minutes.
• Allow to cool in the fridge for a minimum of 2 hours, then sift powdered sugar over the top before cutting into 16 pieces.

Steps:

• Wash the oranges and lemon thoroughly. Cut the oranges into 1/8-inch slices using a mandoline, removing the seeds as you go. Stack the orange slices and cut them into quarters. Place the oranges into an 8-quart stainless steel pot. Add the lemon zest and juice and the water to the pot, set over high heat and bring to a boil, approximately 10 minutes. Once boiling, reduce the heat to maintain a rapid simmer and cook, stirring frequently, for 40 minutes or until the fruit is very soft.
• While the fruit is cooking, fill a large pot (at least 12-quart) 3/4 full with water, set over high heat and bring to a boil. Place 10 (8-ounce) jars and rings, canning funnel, ladle, and tongs into the boiling water and make sure the water covers the jars by at least an inch. Boil for 10 minutes. Turn off the heat, add the lids and leave everything in the pot until the marmalade is ready.
• Meanwhile, place a small plate in the freezer. Increase the heat under the orange mixture to return to full boil. Add the sugar and stir the mixture continually, until it reaches 222 to 223 degrees F on a deep-fry or candy thermometer, and darkens in color, approximately 15 to 20 minutes. You may need to adjust the heat in order to prevent boil over. Test the readiness of the marmalade by placing a teaspoon of the mixture onto the chilled plate and allowing it to sit for 30 seconds. Tilt the plate. The mixture should be a soft gel that moves slightly. If mixture is thin and runs easily, it is not ready.
• Remove jars from the water and drain on a clean towel. Place a canning funnel onto the top of 1 of the jars and ladle in the marmalade just to below the bottom of the threads of the jar. Repeat until all of the mixture has been used. The amount of marmalade may vary by 1 to 2 jars. Wipe the rims and threads of the jars with a moist paper towel and top each with a lid. Place a ring on each jar and tighten.
• Return the jars to the pot with boiling water, being certain that they don't touch the bottom of the pot or each other. (If you don't have a jar rack, try a round cake rack, or metal mesh basket. Even a folded kitchen towel on the pot bottom will do in a pinch.) Add additional water if necessary to cover the jars by at least an inch. Boil for 10 minutes. Using canning tongs, carefully remove the jars from the water, place in a cool dry place and allow to sit at room temperature for at least 24 hours before opening. Once open, store in the refrigerator. Unopened marmalade will last for up to 6 months.

Steps:

• Cut the oranges and lemons in half crosswise, then into very thin half-moon slices. (If you have a mandoline, this will be quite fast.) Discard any seeds. Place the sliced fruit and their juices into a stainless-steel pot. Add 8 cups water and bring the mixture to a boil, stirring often. Remove from the heat and stir in the sugar until it dissolves. Cover and allow to stand overnight at room temperature.
• The next day, bring the mixture back to a boil. Reduce the heat to low and simmer uncovered for about 2 hours. Turn the heat up to medium and boil gently, stirring often, for another 30 minutes. Skim off any foam that forms on the top. Cook the marmalade until it reaches 220 degrees F on a candy thermometer. If you want to be doubly sure it's ready, place a small amount on a plate and refrigerate it until it's cool but not cold. If it's firm -- neither runny nor too hard -- it's done. It will be a golden orange color. (If the marmalade is runny, continue cooking it and if it's too hard, add more water.)
• Pour the marmalade into clean, hot Mason jars; wipe the rims thoroughly with a clean damp paper towel, and seal with the lids. Store in the pantry for up to a year.
