The Wikipedia page on Candlenut mentions an alleged edible, bitter-free Candlenut from Costa Rica, but doesn't provide a reference. "The Carbon Farming Solution" by Eric Toensmeier mentions one edible variety (¿the same one?) called "Maewo", but while he does provide a reference (Ibid., 49), he doesn't mention where it's from, and I couldn't find the reference in a simple internet search.
Does anyone here grow an edible variety? And I mean fully edible, bitter-free, not the usual varieties that are used sparingly as a condiment in food.
And just for reference, what's it like to eat the usual varieties?
