Is it possible to burn honey?

Yes, it is possible to burn honey. Honey is a sugar, and like all sugars, it can be caramelized and eventually burned if heated to a high enough temperature. The Maillard reaction, a chemical reaction between amino acids and reducing sugars that gives browned food its distinctive flavor and color, is responsible for this process. When honey is heated, the sugars in it react with the amino acids to produce a variety of compounds, including melanoidins, which are responsible for the brown color of honey. However, if honey is heated to too high a temperature, the Maillard reaction can progress too far and the honey can become burnt and bitter.
