Hi can't recall which shop sells things like Cocoa Powder and Extracts I thought it was the Food Market am I correct and just unlucky to find any in stock or am I looking in the wrong shop??

You're right, it's the Food Market that has Cocoa Powder, Extracts, and items like Baking Powder and Baking Soda. They sell out SUPER quick so yes, you're probably just not seeing any in stock because they're sold out.

Some items can be found in other stores, like sugar packets and porridge in Quick Bites, etc.

Edit: There's a baking guide thread here, but I guess it's still incomplete and doesn't list where items are sold yet, unfortunately: The Baking Guide [Updated 6/12]

I'm sure SubetaLodge will have information on where each item can be found.

if you don't mind wasting some WT, you can get a lot of stuff from Food Shop and other food shops via Celebration Gift. Me, I figure Allard pays me sP to to his quests so the WT are free, so it doesn't matter that the Vend is not too profitable to me. My eaterpet Procrustes has eaten many of the new food releases by doing this.

Thank you so much for the info was starting to go batty trying to work out where the stuff was lol!

was thinking of that earlier so probably the way to go!

Yeahhhhh. You kind of have to get there RIGHT on the restock or you're sunk. Like Solsticesprite, I also sometimes swing past Celebration Gift in the hopes of getting a few ingredients and then I hoard whatever I do find like crazy.
