One incredible quality of honey is it’s shelf life. If honey has crystallized, it has not gone bad! The sign of crystallization is actually a good thing. Once honey is heated past 140, it slows down crystallization time dramatically but it also destroys beneficial properties in the process. We do not heat Mrs. Angie's Farm Fresh Honey in order to maintain natural benefits. If Mrs. Angie's Farm Fresh Honey begins to crystallize, just keep in mind that it ensures that our honey is a raw, unfiltered product. To re-liquify honey, simply place the container in warm water for about 15 minutes. Once warmed, the honey will return to a liquid state. Do not microwave honey.
