The summertime classic! What’s better than a generous, gooey smear of raspberry jam on a muffin, biscuit, or piece of toast? This recipe is pretty versatile—it will work for a variety of berries. Try substituting blackberries, boysenberries, dewberries, loganberries, or youngberries if you prefer.

Raspberry Jam 

3 pounds (10 cups) raspberries
1 tablespoon grated lemon zest
2 teaspoons fresh lemon juice
3 cups sugar, divided
5 teaspoons calcium water (see note)
5 teaspoons Pomona’s Universal Pectin powder

1. Place the berries, lemon zest and juice, and 1 1/2 cups of the sugar in a medium saucepan over medium heat. Stir and mash until mixed well. Once the berries come to a boil, turn the heat to low and simmer for 20 to 30 minutes. Stir occasionally to keep the bottom from burning.

2. After simmering, you will have approximately 2 quarts (8 cups) of raspberry mixture. Strain half (1 quart or 4 cups) of the berry mixture, which should yield about 3 cups. Discard the seeds and pulp. Pour the strained berries back into the saucepan with the unstrained berries and add the calcium water. Bring the mixture to a boil.

Using Pomona's Pectin requires much less sugar to "jell" your preserves than traditional pectins, giving you a more "true to the fruit" taste. You can even use alternative sweeteners. Pomona's Pectin is available on Amazon.com.

It's too bad Mother Earth News doesn't actually monitor comments on their articles. As Emma Boyce posted years ago - and no one has bothered to answer - there is supposed to be a "note" about "calcium water following the recipe. Of course, there isn't. If one searches the Internet enough, you finally find out that Pomona’s Universal Pectin powder comes with a little packet of calcium powder in it that you mix with water to make "calcium water" to mix into your recipe. The more common brands of pectin, like Sure-Jell and Certo, apparently have some calcium in their mixes so you don't have to go through this separate step.

Could not find the "Calcium water" without which the recipe is totaly useless.
