The article you posed says "...there is no litmus test that consumers can do at home to spot fake honey as only trained experts, chemists and laboratory technicians can check the purity of bee products. This is done by determining the pollen content in the honey sample." What test is that you are showing (that the article says doesn't exist)? What is supposed to be happening in the photo? @EandN thought you might be interested in this conversation.
If honey dissolves in water, is it fake? Scientists cast doubt on DIY 'purity' test The headline from an interesting article on this subject. The consensus of this report is that there is no real test because honey can be different in so many ways. The report is from a scientist from a centre in Australia where they test for honey and impurities added by asian markets. Their conclusion is that there is that all the "Home" tests are worthless. All they do is differentiate between the various purity factors that exist in the formulation and production of honey.
