Sugar-Free Raspberry Jam

  

Sugar-Free Raspberry Jam in a Sugar-Free, Low-Carb Linzertorte

                                  
 
Red raspberry jam is such a lovely treat on toast.  It is also a vital component in the classic Austrian pastry called Linzertorte.  

I had a yen for Linzertorte, so I decided to splurge and make a small batch of raspberry jam.  The jam was delicious.  The resulting Linzertorte was amazing - and with one torte the jam was all gone!  Of course, I had to make more jam so I could make more Linzertorte...

The Linzertorte recipe will follow, after I've had a chance to make another one and perfect the recipe.  Meanwhile, summer is here - we'd better make the jam while we can!


As always, check the proportions in your low-sugar pectin package; I used Pomona Pectin, an apple derived pectin made especially for low-sugar or sugar-free jam.

Sugar-Free Raspberry Jam

4 1/2  cups mashed organic red raspberries (about 8 small baskets)
2 1/4 tsp calcium water (Pomona Pectin - an activator for the pectin)

2 1/4 tsp low-sugar pectin
1 1/4 cup erythritol+ 2 TB
2/3 cup xylitol
14 tiny scoops stevia powder

yield:  2 pint jars plus 3 half pint jars

1. If the jars are brand new, wash them and the rings and lids to remove any chemicals left from processing. If they have been sitting in the basement, check them for dust, and wash off any you find. Put the jars and rings into a stockpot or canning pot and fill with hot water to cover by an inch or two. Put them on the rear burner of the stove over high heat and bring them to a boil. When they come to a boil, turn the heat down and keep them hot and ready.  Be sure to scald the wide-mouthed funnel and ladle, too. 

2.  Following the instructions in your low sugar pectin kit, make calcium water. (I use Pomona brand.)



3.  Pick over the berries and remove any that are moldy.  Put the rest into a large measuring cup, and mash them well.  Use the amount of mashed fruit you have to determine how much calcium water, pectin, and sweeteners to use. 

4.  Put the raspberries and calcium water into a saucepan big enough to comfortably accommodate the whole batch.  Don't fill the pan too close to the top.  Bring the fruit to a boil over medium low heat, stirring frequently to prevent scorching.

5.  Meanwhile, measure the sweeteners and the pectin into a medium sized bowl and whisk them all well to combine.

6.  When the fruit comes to a full boil, get a long-handled wooden spoon ready, and gradually add the sweetener mix to the hot fruit, stirring constantly as you pour in the sweeteners. Stir well and frequently to dissolve the pectin and sweeteners and prevent lumping. Bring it back to a full boil. When it looks lovely and thick, turn off the heat and get ready to can. (Don't worry if it isn't as thick as jam; it thickens as it cools.)

7.  Clear a good sized work surface near the stove, and cover it with clean dishtowels (preferably ones you don't care about!)

Turn the heat off under the pot of jars and move it to the front of the stove so you can reach them easily, and move the jam to the back of the stove so you don't get water into it by accident. (Put the lid on the pot if necessary.) Using tongs or a jar lifter in your dominant hand, and a clean dishtowel in your other hand, carefully remove the lids and rings and drain them on the towels. Lift each jar out of the hot water, dump the hot water back into the pot, and carefully guide and transport the hot jar over to the towels. Turn it upside down to drain out the extra water. Repeat until all of the jars are drained and ready.

Turn the heat back on high underneath the pot that the jars came out of, and bring it back to a full boil while you can the jam.

Now, again using your tongs (or a clean towel, oven mitts, or tough hands!) turn the jars right side up, and line them up to be ready to fill. If you have a wide-mouthed jar funnel (which I so highly recommend - available at any good hardware store, Bed Bath and Beyond, well stocked grocery stores, etc., for less than $5) put it on top of one of the jars.

Grab your best ladle, and bring the pot of hot jam over to your work surface. Carefully fill each jar, leaving 1/4" of space at the top. If you have a wide-mouthed funnel, the bottom should come to just the right spot. If you don't, do your best! If necessary, spoon some out to reach the right level. After you have filled all your jars, use a clean, moist towel to wipe the ring area and the top surface of the jars clean. If you have less than a full jar of jam, put that one straight into use and don't bother to can it.

Put the lids on, followed by the screw tops, and screw them down.

 8.  Bring the pot of water back to a full boil, and carefully return the full jars of jam to the pot.  You may have to remove some of the water, as full jars displace more water than empty ones.  Bring the water back to the boil again, and boil for 10 minutes.

9.  Remove the jars and let them cool on the towels.


Notes from Christine:

"What's with all of these obscure sweeteners?" Erythritol and Xylitol are sugar alcohols; super low-glycemic, super low-calorie, super low-carbohydrate, and good for your teeth.  

Xylitol is a little sweeter than cane sugar, has a fairly neutral flavor with a little bright, almost pepperminty quality, and can be found easily at a well-stocked health food store or really good grocery store.

Erythritol, very neutral in flavor, is about 60% as sweet as sugar, and is very difficult to find in stores, except in individual packets. As it is 60% as sweet as sugar, it takes quite a bit more to reach the right level of sweetness in a recipe, and this makes proportions difficult.  However, its very neutral profile makes it a natural for blending with xylitol and stevia, especially since stevia is so highly concentrated.  It's worth tracking it down by mail-order, or you could make a special request to a grocer to order some for you.

Stevia is a natural, calorie-free leaf extract, super concentrated and very sweet, but with a weird, bitter aftertaste and no volume; due to its highly concentrated state, one teeny-tiny scoopful (which comes in its container) is equal to a teaspoon of sugar. It is easily purchased at Trader Joe's or any grocery store.

Be aware that some Xylitol and Erythritol brands in American packaging are actually imported from China and repackaged. That is why I buy all of these directly from Xylitol USA, http://www.xylitolusa.com/ which manufactures them from North American sources.
