All natural honey will crystalize sooner or later. Crystallized honey is spreadable and will melt in hot tea or coffee. If you prefer liquid honey you may heat it up in a double boiler. In order to make the crystalized honey liquid by the help of a microwave oven, you remove the lid from the glass jar and heat at medium for 30 seconds. If you heat up the honey too much, it will lose its wonderful taste and natural enzymes.
