White foam is often greeted with the words: "What's that white stuff on the top"? If you find the white foam in your honey jar, consider yourself lucky.
Honey foam may be one of the most surprising things about the appearance of raw honey. Raw honey usually has a slight layer of white foam on the surface, marble-like swirling or white spots in the upper sides of the jar. This is caused by air bubbles that have risen to the top. It is a sign that the honey has been packed without heating.
Honey foam is delicious. It is light, flavorful, and packed with air bubbles that have trapped some of the wondrous stuff that is in raw honey: pollen, propolis, wax, and, of course, raw honey.
