From what I can tell, you want to look at the progress gauge as it "cooks." I think there's 10 lights that glow as it's being made, with 10 as "success." It's a superfail if it fails below... 3-4? I don't know exactly.
I'll change this signature when Final Fantasy becomes good again. Guess this sig will be here forever, it's been kinda meh ever since it left the SNES!
Try harder! It works on 4chan, should work on this game as well! XD
Nah, seriously now, the best way to make it is to try some recipe needing a huge skill level, much earlier than you should on the game. And using rare ingredients too. I had it once when I tried to make a Gold Juice.

Clasni is on the money for that one. Make fails then mix them. I put rocks into a blender when I have a really low cooking skill and it turns out to be a Super Fail, but I noticed that when you get a higher cooking skill, that SEEMED to change it and cause it to be a Fail Dish instead of a super.
