Raspberry Lime Jam

Aside from making pickled green beans occasionally with my mother when I was a kid, I have practically no canning experience. But, I've been reading Food in Jars since Marisa started sharing her expertise with all of us, so I figured berry season was the perfect time to join in the fun. I wanted to use local fresh fruit and as little sugar as possible so I could enjoy my jam without hesitation. I also added a twist to a plain raspberry jam by adding a significant citrus kick with lime juice and the powerful zest.

I had lots of traditional pectin around my house, but grabbed a box of Pomona's Universal Pectin at Whole Foods at the last minute for this Raspberry-Lime Jam. Pomona's pectin calls for making a calcium water to aid in gelling and they supply the calcium powder with every box of pectin. You simply add a little calcium powder to some water and stick it in the fridge before you start jamming.

I'm also going to give just the basic canning instruction here, if you've never done it before check out your copy of the Joy of Cooking or one of the online resources recommended by Food in Jars.

4 cups ripe red raspberries
3/4 cup sugar
2 tablespoons lime juice
Zest of one lime
2 teaspoons calcium water
2 teaspoons pectin

Wash and mash your berries. This is easy enough to do with a fork to ripe raspberries. Combine mashed berries, lime juice, lime zest and the measured calcium water in a medium pot and bring to a boil. In a separate bowl mix the sugar with the pectin and add to the boiling fruit. Stir vigorously for two minutes to dissolve the pectin and bring jam back to a boil and remove from the heat.

Carefully fill your sterilized jars to 1/4 inch of the top. Wipe the rim of the jar clean, place on the lid and screw on the band. Then process in boiling water for 10 minutes. Remove the jars from the water and let cool completely, about 12 hours.

My yield was about 4 1/2 cups of finished product. Delicious finished product.

    thank you for this! i just made orange marmalade and had never canned before. not sure if my canning work was really tops, but oh well. the marm came out a little too sweet for my taste so i'm going to have to try that pectin instead.
