Cranberry Port Jelly – Questions and Concerns

Cranberry Port Jelly – Questions and Concerns
Yesterday, I made Ball’s Cranberry Port Jelly, and I ran into a few unexpected issues that I’m hoping to get some insight on. Before processing in the water bath, I carefully measured the headspace at ¼ inch. However, 24 hours later, nearly all of the jars appear completely full. I also noticed more siphoning than expected, with residue visible on the jar rings. Has anyone else made this recipe and experienced something similar?
I have a few specific concerns:
1. Difficulty removing air bubbles
Debubbling was extremely challenging. Every time I used the debubbling tool, it pushed the jelly upward, almost causing it to overflow. Is this common with jams and jellies? This is my first time canning either, so I’m not sure what’s typical.
2. Jelly thickness before canning
The mixture was very thick when I filled the jars. I followed the recipe timing exactly, but I’m wondering if I may have over-reduced it. Should jelly already have a firm, gel-like consistency before going into the water bath, or is it supposed to be looser at that stage?
3. Much higher yield than expected
The recipe stated a yield of four half-pint jars, but I ended up with seven half-pints plus one quarter-pint. I double-checked all measurements and followed the recipe precisely. While straining the jelly, I noticed a significant amount of liquid remaining, so I pressed the mixture through the mesh strainer much more firmly. Could this have been the issue? Is it possible that I forced too much pulp or fine solids through, which shouldn’t have been included?
4. Safety concerns
Are any of these issues potential food safety concerns? Has anyone else had a similar experience with this recipe?
Overall, I’m feeling a bit perplexed because I was extremely careful about maintaining the correct headspace. It’s possible I overcorrected by filling the jars too full. I may be overthinking this, but since these jars are intended as Christmas gifts for family, I want to be absolutely sure everything is safe and done correctly.
Many thanks, as always, to this wonderful community for any advice or insight!
