apricot refigerator jam

We made refrigerator jam this morning, and it seems to have set!  We followed this recipe, pretty much, but halved it.

And we didn't can it--we just poured it into jars and let them cool on the counter and put them in the fridge.  It made about a pint and a third of apricot jam.

(I was alarmed by how much the Pomona's Universal Pectin costs at the co-op, but I guess that's the price you gotta pay for low sugar.  And I was surprised by how much organic frozen apple juice concentrate costs at the co-op too--more than $4!  Maybe I'm stuck in the past.)

Here are my notes for next time.

Wash, pit, finely chop apricots.
Three cups in pan with 1/4 cup lemon juice.
Add four tsp calcium water.
In a separate pan:
one cup apple concentrate--boil.
Add 3 tsp pectin and blend well.
Boil apricot mixture.
Add apple juice mixture to apricot mixture.
Return to boil and remove from heat.
DONE

Calcium water: half tsp calcium powder in half cup water.
