First, you need to repeatedly fail recipes. Like, really fail, not 2-star or 3-star when you're looking for "perfect". Eventually he'll get so mad you will be transported to a map where you have to fight a "Furious Ritzy" boss. He drops "Master Chef Feedback" etc items.
Once you have these items in your inventory, Chef Ritzy's face next to your "Try Again?" button will no longer be grayed out. Click on it to get detailed feedback on each of your ingredients' quantities. They get a score 0-4 depending on how far you are from the perfect amount.
You can't do this endlessly, even if you have the feedback items. At some point he starts saying, "You're going to wear out my tastebuds by asking for so much feedback" and he won't give any more until daily reset.
Also, it seem the "perfect" recipes only give 4 stars, not 5. So we have to perfect all 33 recipes to get the final medal and chair.
if any of you guys are going to quit ill accept all of ur equips and mesos, thanks n.n love all of yall
Quit? Why would we quit? This is the best boss in the game right now.
Consider:
1) Equally difficult at all funding levels
2) Unlimited daily clears - to get more entry tickets, just attempt one of the following quests: "Visit Cash Shop", "Change Channel", "Fight Inferno Wolf", "Use Boss Queue", and many, many more (have fun discovering them all yourself!)
3) Rewards: as much exp, meso, and valuable drops as you can farm in the boss's bonus stage, a.k.a Maplestory!
