Anecdotal but everything in that NPR article rings true to me. American consumers are used to the bear shaped bottles with purified honey that’s barely distinguishable from sugar syrup and could easily be adulterated but the raw honey I usually buy is so obviously honey from the taste and texture that I have a hard time believing any of it is adulterated. If honey producers were really that good at artificially replicating flavor profiles, they’d be far ahead of the rest of the food science industry.
