Tell us about yourself!
At 140 degrees you've over cooked it and it no longer carries the same benefits as the original honey. If you are using store bought big manufacturer honey, probably wasn't raw anyway. Best way - warm up a bowl of water (not boiling) and put your jar of honey into it. Possible to warm a hand towel and wrap it around your jar to get it to dissolve as well. Note, once you cook as mentioned above, it continues to crystallize.
