To finish this quest: Get the ingredients from the kitchen around him (soup, fish, wine). Then combine them in your inventory by setting the soup next to an item.

For example: Set the soup next to the fish and a + (plus symbol) will appear on the soup to combine into a new dish that you can turn in to finish the quest.

Note: Make sure auto arrange of inventory is off when trying to combine the new soup.

Keep in mind that the invetory combining doesn't work with "Auto Arrange" - Make sure it's un-ticked.

Bland Soup + Wine = Good Smelling Soup (All that quest completion requires)

Vintage Wine, Aged Wine, Fish... what else am I missing and where?
