Raw honey will naturally crystallize with time. This is fine, and it doesn’t mean the honey is spoiled or unsafe to eat. It will still spread on toast or drop into tea by the spoonful, if you can get it out of the jar. But if you prefer your honey liquid, or have a crystallized squeeze bottle, this can be fixed.
A quick Internet search may tell you to microwave your honey or place the jar in very hot water. These methods may work, but if you made a point to buy raw honey with all its enzymes and beneficial compounds intact, you don’t want to lose those benefits when you liquefy it. Microwaves can melt plastic, and too much heat can affect the honey’s taste and nutrition.
So what can you do? Take your time and treat your honey gently. Putting the jar in hot water is the right thing to do, but be careful not to heat it too much. To preserve the flavor, color, and nutritional content of your honey, you need to keep it right about 100 degrees. Honey doesn’t conduct heat well, though, so it may take quite a while at that temperature to dissolve all the crystals. A good plan is to fill a bowl or pot with water that would make a comfortable bath, place the jar in the water, and be prepared to replace the water frequently for a few hours. Stir the honey every so often to help distribute the heat. Practice a little patience, and then enjoy your golden, liquid honey!
