Pure, raw and unheated honey has a natural tendency to crystallize over time with no effect on the honey other than color and texture. What's more, the crystallization of honey actually preserves the flavor and quality characteristics of your honey.

Can you still eat honey when it is crystallized?

Crystallized honey becomes whiter and lighter in color. It also becomes much more opaque instead of clear, and may appear grainy (1). It is safe to eat.

How can you tell real honey from fake?

–Water Test: In a glass of water, put a spoon of honey, if your honey is dissolving in water then it's fake. Pure honey has a thick texture that will settle at the bottom of a cup or a glass. –Vinegar Test: Mix a few drops of honey into vinegar water, if the mixture starts to foam, then your honey is fake.
