Lots of good advice. Summarizing your options:
Option 1) Use it in cooking. Think BBQs, meat sauces, stir fry, wings, jerk seasonings, .., those sorts of things.
- Put in smaller containers and freeze it. Cold stops the process. Use up in foods.
Option 2) Make mead. Lookup some recipes, dilute, add some more yeast, and wait. Mead may be tricky as you do not know the starting point because it is already partway along.
Option 3) Feed to livestock. Do you have pigs? Mix it into their slop. Gets used and no waste ;)
Option 4) Dump out. Take out into the back bush somewhere and dump it. The various wildlife feed on and take care of it.
What not to do. Do not heat it. The off taste will get stronger. Do not feed it to your bees for winter. Winter stores need to be the best feed not scraps. To remotely consider as feed, it would be diluted with water then open (rob) fed in the Spring.
Personally, over here it would be option 1 or 4.
If there is honey left over in the pantry then either: the cook needs a good talking too about using too much sugar and instructed to be using honey. Or if just too much volume then sell or give away. A jar of honey always sweetens relationships :)
