If you /really/ want to be sure, buy comb honey. Impossible to fake.

Can't fake honeycomb be made and placed in to jars of fake honey?

I think the market is probably too small to put the money into figuring out how to fake it convincingly. Also the market leans towards enthusiasts who detect fakes more readily than the average honey normie.

If it ever becomes mainstream this will definitely happen.

Cost/reward is likely sufficient disincentive.]

This is shades of "if you can fake sincerity you can fake anything":

I've seen it but never dared to buy. What do you do with the honey comb, eat it? Does it taste waxy?

The comb walls are basically like chewing gum. It does not have much taste.

Yes you can eat it and you spit out the wax. The wax is a bit flaky so I didn't find it that pleasant to chew on. Some people apparently spread it in toast like jam and eat it wax and all. It's not great for stirring into drinks.
