Triple Citrus Marmalade was created by Lindsay Landis and reprinted with her permission from the Winter edition of That’s My Jam, her set of 4 e-books. Lindsay loves making jam, in addition to cooking and baking. Her blog, Love and Olive Oil, has additional jam and jelly recipes as well as many other delicious recipes.Lindsay says: “Three times the citrus, three times the charm. This brilliantly hued marmalade is made with ruby red blood oranges, blush pink cara cara oranges, and deep yellow Meyer lemons. You can use any assortment of citrus you like, about 3 pounds worth, as long as you have 2½ cups of citrus ‘stuff’ to work with.”
Servings 4 cups
- 1¼ pounds blood oranges
- 1¼ pounds cara cara oranges
- ¾ pound Meyer lemons
- 2 cups granulated sugar divided
- 2 teaspoons Pomona’s pectin powder mixed with 1 cup sugar
- 1 cup filtered or spring water
- 2 teaspoons calcium water see step #1
- Before you begin, prepare calcium water.To do this, combine ½ teaspoon calcium powder (in the small packet in your box of Pomona’s pectin) with ½ cup water in a small, clear jar with a lid. Shake well.Extra calcium water should be stored in the refrigerator for future use.
- Wash jars, lids, and bands. Place jars in canner, fill canner 2/3 full with water, bring to a boil. Turn off heat, cover, and keep jars in hot canner water until ready to use. Place lids in water in a small sauce pan; cover and heat to a low boil. Turn off heat and keep lids in hot water until ready to use.
- Wash and scrub citrus, then fully zest using a ribbon zester. Cut off pith, then segment fruit, discarding seeds. Squeeze out remaining juice from membrane. You should have a total of 2½ cups citrus zest, pulp, and juice.
- Whisk together 1 cup of sugar with pectin until evenly distributed; set aside.
- Pour prepared citrus and water into a large, heavy saucepan. Bring to a boil, then reduce heat and simmer, covered, for 10 minutes or until softened. Add calcium water and increase heat to bring back to a full rolling boil.
- Whisk in sugar/pectin mixture, stirring vigorously until completely dissolved and mixture returns to a boil. Whisk in remaining 1 cup sugar, stirring until dissolved, and then bring back to a full rolling boil once more.
- Remove from heat and ladle jam into hot jars, leaving 1/4-inch of head space. Wipe jar rims and screw on lids. Process for 10 minutes, then transfer to a wire rack to cool completely. Check seals; lids should be sucked down. Eat within 1 year. Lasts 3 weeks once opened.
