Why your jar has gone cloudy (and why that's good news)
Crystallised honey isn't spoiled honey. A short explainer on what's happening in the jar and the ten-minute fix.
Every few weeks someone messages us, slightly concerned, with a photo of a jar gone pale and grainy. The honey, they think, has gone off. It hasn't. Crystallisation is the most natural thing a real honey can do, and here is why.
Honey is a supersaturated sugar solution
There is more sugar dissolved in honey than the water can comfortably hold. Over time — weeks, sometimes months — the glucose part of that sugar drops out of solution and forms tiny crystals. The jar turns cloudy, then pale, then sets firm.
Different honeys crystallise at different speeds. Anything with more glucose (clover, blackwattle, canola) goes hard quickly. Anything with more fructose (most eucalypts, manuka) stays liquid for much longer. The same hive can produce both within a few months of each other.
It is a sign you bought the real thing
Supermarket honey often doesn't crystallise because it has been heated hard enough to dissolve every last crystal and ultra-filtered to remove the pollen and wax fragments that crystals like to form around. That same process is what flattens the flavour.
A jar that goes cloudy in your cupboard is a jar that hasn't been cooked. Take it as a good sign.
The ten-minute fix
Stand the closed jar in a bowl of warm — not hot — tap water for about ten minutes. Stir, and it will loosen back to liquid. Don't microwave it and don't put it on the stove; high heat damages the same aromatics you bought the honey for.
Or, honestly, just leave it. Set honey is wonderful on warm toast and easier to spoon onto porridge without dripping. Half of our kitchen jars end up set by the time we finish them.
