I wasn't on the test server, so I'm not really sure what broth is what pet. All jugs are cooking recipes.
Wormy Broth: Little worm, shell bug. (Pretty sure this is frog) Recruit rank
Briny Broth: Hamsi, Mercanbaligi, Rhinochimera (Penguin?) Craftsman rank
Lucky Broth: Gelatin, Buffalo Meat, Abaia Artisan rank
Shadow Broth: Dragon Meat, Nopales, Agaricus Adept rank
Looks like shadow and lucky broth will be annoying/expensive to get. Abaia is a legendary fish which can only be caught with Ebisu or Lu Shangs (and can break Lu Shang's) in a pond in Jugner Forest (s). I knew I shouldn't have sold all the dragon meant I was getting in gold chests....
