I put all the cobs in my bid stockpot and covered them with water... brought the water to a boil, lowered the heat and simmered them, covered, for two hours.
I then drained the liquid into another pot and discarded the cobs.
I stirred in the sugar(s), brought the mixture to a boil, and boiled gently until the mixture reduced and thickened to a syrup consistency.
Meanwhile, I washed, sterilized, and heated my jars and lids (I used half pint jars).
Once my syrup had reached the thickness I wanted, I added a little vanilla extract (optional) and filled my jars, leaving a half inch headspace.
I wiped the jar rims with a damp cloth and tightened on my lids to fingertip tightness.
I processed my jars in a boiling water bath (covering the jars with water) for 10 minutes.
After processing, I removed the jars of syrup using my jar lifter and set them on a folded dish towel on the counter to cool and to listen for the PING of each successfully sealed jar.
The syrup will be yummy on pancakes or waffles... and I'm sure there are other uses I haven't come up with yet!
I even saved the silks for a medicinal tincture! But that's another story for another day!
