If you think that all food items have a use-by date, then sadly you’re mistaken. There is ONE food item that has been proven to never spoil and that food is pure, unadulterated honey.
Yes, the golden syrup that bees tireless make is the only food that does not go off. Would you believe that honey found buried alongside King Tutankhamun was still edible? The reason for this is that honey has a very high sugar content and has inherent antibiotic properties that act as its own preservative. If stored incorrectly, honey may become cloudy (due to the crystalization of sugar) but this does not have any effect on the food product. If the honey stored in your cupboard has become cloudy, put the honey jar in warm water and stir constantly or transfer the honey in a microwave-safe jar and microwave it on medium power (with the lid off) stirring every 30 seconds until the crystals dissolve. If moisture gets into the honey, yeast may grow and ferment – this will not spoil the honey per se, but the honey will taste sour.
To prevent crystalization and the possible fermentation of honey – make sure you store honey in a cool, dark area and keep the lid tightly capped after each use.
