Q&A for How to Decrystallize Honey

All you need to do is warm it up. When you warm up crystallized honey, its viscosity will increase, which will make it easier to work with.

Forever, because honey doesn’t expire.

The temperature in an active beehive reaches 95° F regularly (the bees actually work to keep it to that temperature). Raw honey, which has (at least theoretically) the most nutritive value, can be heated to that temperature. Heating honey hotter than that will alter some of the enzymes in it, but it doesn't harm the honey - it's still delicious and healthy. If you boil honey (bubbling hard) for over four hours, it apparently can grow substances that in large amounts may be carcinogenic - but for any normal use, no, there's no problem with heating honey.

Yes. Honey doesn't expire. Sometimes honey is cloudy, especially "creamed" honey.

Your lid does not have a gasket that really works. Try a different container.

Cut open the plastic bottle and transfer it in to a cafetiere (French press) glass jug for the warming in the pan. You can then store it in an empty balsamic vinegar bottle (cleaned, of course).

You should not microwave honey. As explained in the warning section, microwaving honey destroys its beneficial enzymes and therefore removes the health benefits of honey.
