If honey becomes crystallized (solid) has it gone ‘bad’?

Honey does not spoil. Crystallized honey is caused by the glucose in liquid honey becoming a solid. Honey can be consumed in its crystallized form or you can warm the honey to dissolve the crystals by placing the jar in warm water and stirring until the crystals disappear. Do not boil or scorch the honey. – Nancy Ostiguy, Pennsylvania State University
