Main Walkthrough

Location: The Hideaway (ship)
Petitioner: Yvan, Kitchen Hand
Unlocked: Complete Black Light Burns
Reward: Badge of Mettle +1, 10 Renown

In order to trigger this side quest you first need to complete the main quest Black Light Burns, during the second act of Final Fantasy XVI. Get that far into the story and you'll find A Culinary Pilgrimage waiting when you return to the Hideaway.

Head to the Ale Hall, on the east side of the Main Deck. Here you'll run into Yvan, a kitchen hand. He's busy reading a tome on monstrous recipes, and he wants Clive's help creating one of the recipes. The clue he provides points Clive towards Martha's Rest, where you'll find a Flesher by the lift. The Flesher will reveal that the recipe is talking about scorpions.

Head into Three Reeds via the southern bridge out of Martha's Rest. Travel east, across a much smaller bridge, and continue east until you see a clearing populated by a group of Lowland Scorpions. Engage and take them out. These things aren't too bad, though a single sting will incapacitate Clive for several seconds, so watch your step.

You'll receive five Unwonted Violets for besting the Lowland Scorpions. Take them back to Yvan and he'll reluctantly cook them up. Quest complete... for now.
