I’ve gotten a couple of questions lately about the loss of syrup when canning whole fruit. Here’s the story. From what I’ve found and read, the loss of syrup isn’t a major problem unless the jars loses multiple inches. Ideally, you don’t lose too much in the processing, but sometimes it happens that upon removing the processed jars from the water, some liquid will bubble out as the air escapes (the official word for this loss of liquid is siphoning). However, as long as the jars sealed, you should be okay. You may get some discoloration in the fruit if you wait a long time to eat it, but if you use it in the next few months, you shouldn’t notice any loss in quality.
For next time, try to do a more complete job of removing the air bubbles from your jars before processing. Make sure the sealing compound in your lids is quite soft and tighten the rings more tightly than you typically do. Also check and ensure that your jars are completely covered with water during processing, as low levels can increase the chance of losing the liquid from your jars.
And, if you haven’t figured it out from the picture above, you can also can Seckel pears (the tiny, crispy ones) whole, just like the plums I did a couple of weeks back. The only change I made to the recipe was that I added a couple of teaspoons of powdered ginger to the syrup, for a slightly different flavor profile. I can’t wait to open those babies up!
