|Crushed Boysenberry Jam|
Amount Measure Ingredient -- Preparation Method
|-------- ------------ --------------------------------
2 quarts rinsed boysenberries - (lightly packed)
3 cups sugar -- or to taste
3 tablespoons lemon juice
Combine the berries, sugar and lemon juice in a large nonaluminum bowl.
With a potato masher or large metal spoon, press gently on the berries to
bruise and lightly crush them. This allows the juices to start exuding
freely. Allow the fruit to macerate at room temperature for at least 4
hours, stirring occasionally, and as long as overnight (covered and
Pour the contents of the bowl into a wide, shallow saucepan (not unlined
aluminum or iron) and bring to a boil over high heat. With a metal spoon
or fine mesh skimmer, skim off any foam that collects on top and reduce
the heat to moderate. Continue cooking the fruit mixture for 25 to 35
minutes, stirring constantly the last 10 minutes to prevent the jam from
sticking to the pan.
When the bubbles begin to change from large intermittent ones to very
small all-over ones, the jam is ready. The mixture should be reduced by
half and will look like bubbling tar. To test whether jam is ready,
remove 2 tablespoons to a small saucer and place it in the freezer for 5
minutes. Meanwhile turn off the heat under the pan. When the test amount
is cool, it will wrinkle slightly when slowly pushed together with your
finger. If it doesn't, continue cooking for another 5 minutes and test
again. When ready, the jam will be thick but will still flow from a
spoon. You can also test the jam by scooping some out in a metal spoon
and then pouring it back into the pot. When the jam begins to pour out in
a single sheet rather than in several different streams, it's done. The
jam will thicken more while cooling.
Make sure you have clean jars and rims and fresh lids that have never been
used (lids and rims can be purchased separate from jars). Dip every jar
and lid (as well as any other implements that will touch the finished jam)
into a large pot of boiling water for at least 3 minutes. Afterward,
remove them to a baking sheet and keep them in a 250 degree oven until you
are ready to use them.
When the jam is cooked, ladle it into the jars, coming within 1/4-inch of
the top (a wide-mouthed canning funnel makes this easy). Wipe the threads
of the jar clean and place the lid on top of the jar. Screw down the rim
as tight as it will go. Place the sealed jars in boiling water to cover
for 10 minutes.
Remove them to a sideboard and let them cool. You should hear a repeated
"plink-plink" as the cooling jars form the vacuum that seals the lid.
When the jars are cool, test each by pushing down in the center of the
lid. There should be no flex in the lid. If there is, return the sealed
jar to the boiling water for another round. Do not tighten the rims
further. Store jams and jellies in a cool, dark place, such as a pantry.
This recipe yields 5 (8-ounce) jars.
Comments: Boysenberries are a delicious cross between a raspberry and a
blackberry. They are soft and delicate like the raspberry with the
distinct tartness and seeds of the blackberry, often growing to half as
large as your thumb. If the seeds bother you, press about half of the
finished mixture through a mesh sieve in small batches. Because this jam
is not stiff, it will also pour very nicely over vanilla ice cream.
