Calamondin Orange Marmalade

Calamondin oranges are the small but plentiful fruits of a popular citrus houseplant that originated as a cross between a tangerine and a kumquat. They smell sweet, but are surprisingly tart, and make a very refreshing marmalade. This is a very simple recipe, and quite adaptable to other tart citrus such as Meyer lemon or lime. I haven’t tried sugar substitutes with these, but if you have success doing so, please share your secrets with the rest of us!

Serves: 4 half-pint jelly jars full

4 cups orange calamondin fruits (about 40 fruits)
2-1/2 to 3 cups sugar

Step by Step Instructions
  1. Wash the fruits, cut in half, remove any seeds. Put fruit through a food processor or slice thinly with a knife.
  2. Measure chopped fruit, and add 3 cups of water for every cup of fruit.
  3. Place in a saucepan, bring to a boil, and cook for 15 minutes.
  4. Remove from heat, cover, and let stand overnight to develop a fuller flavor. (You will have about 6 cups of "orange stock.")
  5. Stir in sugar (use the 2-1/2 cup amount for a very tart marmalade, or 3 cups for a sweeter one). Cook rapidly to 220 degrees on a candy or jelly thermometer.
  6. Remove from heat and pour into jars. (If you wish to preserve the marmalade, follow approved canning procedures and process for 5 minutes.)
