Well, a quick search for buckwheat will yield more than a few results; in particular, and I write this knowing that you stated that you love the taste of buckwheat honey, you will not find many (if any) fans of buckwheat mead. WAY strong flavor. A very little bit goes a long way.
I know that I'll only add a couple of ounces if at all, and only if the recipe calls for it. But, that's just me!
Some knowledge will never be shared, not from a desire to conceal it, but because it is so common to the individual that it is assumed to be already known.
