So here is his advice. Instead of spending a bunch of time trying to scrape or scoop that foam out, lay a piece of cling-wrap over the foam and just lift it off.
I can't tell you how long I've been dying to try this out, but I finally got my chance. I'd recommend preparing a bowl or something to put the cling film in as soon as you pull it off so that it doesn't drip back into the honey, but other than that, it really is so easy!
There were a few spots where I got a bit of air between the Saran Wrap and honey, so that accounts for the bit of foam that got left behind, but I'm otherwise quite pleased with the results. What do you think? Pretty clean, yeah?
