I’ve learned that the reason why the brand of honey I’ve been buying is so good is that it’s unfiltered and unpasteurized. It gives me a vague sense of unease as I wonder if there’s some good reason why so many producers of the stuff do filter and pasteurize it even though it tastes this much better when you don’t.
Further reading suggests that although the bacteria cannot live in honey, spores which can cause botulism can nonetheless sometimes be found in honey — both pasteurized and raw. Health Canada suggests not giving honey to infants.
