A question of the OP, if I could.
Did you intend this cook-off to be about this, or about this? Your initial post seemed to go in the direction of (or at least encompass) the second one, but so far most of the responses have pivoted to the first one, especially when talking about home-made ones. What is your intention for what this thread discusses?
Even if it is to be the first one, is it to be ONLY about Japanese renditions or facsimiles thereof?
