This recipe for Blueberry Marmalade is from "Woman's Day Encyclopedia of Cooking" (Fawcett Publications Inc.), which is out of print but still available through Amazon and other booksellers. Oranges and lemons join fresh blueberries in this easy marmalade. Using liquid pectin makes it virtually foolproof. It makes a nice gift from the kitchen.

What You'll Need

  • 1 medium orange
  • 1 medium lemon
  • 3/4 cup water
  • 1/8 teaspoon baking soda
  • 4 cups fresh blueberries, crushed
  • 5 cups sugar
  • 1 (6-ounce) package liquid fruit pectin (see the section, below, on substituting dry for liquid)

How to Make It

  1. Peel orange and lemon. Finely chop rind and place in large cooking pan. Chop orange and lemon pulp and set aside.
     
  2. Add 3/4 cup water and baking soda to rind and bring to boil. Reduce heat and simmer 10 minutes, stirring occasionally.
     
  3. Add chopped orange and lemon pulp, blueberries, and sugar. Return to boil. Reduce heat and simmer 5 minutes.
     
  4. Remove from heat and cool 5 minutes. Add pectin; return to a boil. Boil, stirring constantly for 1 minute. Remove from heat and skim off foam with a metal spoon. Pour marmalade into hot sterilized jars, filling to 1/4 inch from the top. Wipe jar rims. Cover at once with metal lids and screw on bands. Process in boiling water bath for 10 minutes.

    Substituting One Form of Pectin for Another

    • It's really not possible to make a one-for-one substitution of pectins. Not only will the results be different, but the cooking method (at what point the pectin is added) will be different as well.
       
    • You can convert dry pectin to liquid by mixing 1 (1.75-ounce) package of dry pectin with 1/2 cup water and boiling for 1 full minute. Pour into a measuring cup and add enough water to make 1 cup. Use in the same proportions as liquid pectin is called for. In this recipe, that would be 6 ounces.
       
    • To substitute liquid pectin for a recipe calling for dry pectin, use 2 teaspoons of dry pectin for every 1 tablespoon of liquid called for in the recipe. But here's the difference, dry pectin should be mixed into the sugar before cooking, to prevent clumping, and liquid pectin is added when the fruit is at the boiling point.

    Do you know the difference between jam, fruit preserves and marmalade?

    • Typically, jams are made by thickening fruit purée until it has an even consistency without big chunks of fruit, bright color and a semi-jelled texture.
       
    • Fruit preserves, on the other hand, have large or whole pieces of sweetened fruits (or vegetables) that are cooked and jelled. It is not smooth like jam or jelly.
       
    • And marmalades are just sweet and tangy fruit preserves that include the flesh and zest from citrus fruits, usually oranges. In this recipe, orange and lemon citrus fruits take a back seat to the fresh blueberry flavor.
