Episode notes
Jam's Stuck Honey Jar
- Jam found an almost-empty jar of honey in his cupboard that had become thick and wouldn't flow when inverted.
- This everyday observation prompted the episode's exploration of why honey crystallizes.
Saturation Drives Honey Crystallization
- Honey crystallizes because it is an extremely saturated sugar solution that will precipitate solids over time.
- Crystallization is the dissolved sugars forming their solid crystal structures as they come out of solution.
Handle Crystallized Honey Carefully
- Treat honey like other supersaturated solutions: given a nucleation site it will crystallize quickly.
- To reverse crystallization, gently warm honey to re-dissolve crystals (avoid overheating plastics).
