Crystallized honey is not spoiled honey. It is honey that got cold, and you can bring it back in about five minutes with a pot of warm water.

I learned this the slow way. For two winters I kept a jar of raw honey on a shelf right above the stove, and every January it turned into something closer to peanut brittle. I threw out three jars before a beekeeper at a farmers market finally stopped me and asked why I was buying honey I clearly was not eating.

Why honey goes solid

Raw honey is mostly sugar with a little water. The glucose in it wants to form crystals, and cool temperatures give it an excuse. Tupelo and acacia stay liquid for years. Clover and dandelion can go grainy in a month.

The five minute fix

1. Fill a saucepan with two inches of water and warm it over low heat. Hot to the touch, not simmering.
2. Set the jar in the water with the lid off and wait five to ten minutes.
3. Stir once or twice. The crystals dissolve from the outside in.

Do not microwave it when you are in a hurry. A microwave heats unevenly, and honey that goes past 140 degrees loses its enzymes and tastes flat. The jar also comes out too hot to grab safely.

One detail that surprised me: stirring alone will not save a jar that is mostly solid. Break it up with a butter knife first, then warm it.

Keeping it pourable longer

Store honey in a cabinet, not the fridge. Cold is what starts the whole process, and a dark spot at room temperature beats any gadget. If you buy in bulk, decant into smaller jars so you only warm what you will actually use this month.
