Doing an excellent job cooking curry will award a higher curry ranking, though Pogobuy not positive on the specifics of those yet, the process includes three steps: Fanning flames, stirring a pot and throwing in your metaphorical heart. A higher ranked curry gives your Pokémon more HP and restores PP. Pokémon get friendlier, too. POGOBUY Will update this post once we figure out how to get that highest curry ranking consistently.

From what we know so far, the rankings are as follows, from best to worst:
1. Charizard Class (Gold): Restores HP, PP, and status conditions. Pokémon gains “a lot” of experience and gets “quite friendly toward you.”
2. Copperajah Class (Silver): Restores HP, PP, and status conditions. Pokémon gains “a lot” of experience and gets “quite friendly toward you.”
3. Military Class (Bronze): Restores HP and status conditions. Pokémon gains experience and gets friendlier.
4. Wobbuffet Class: Restores HP by half. Pokémon gains “a few” experience points and gets friendlier.
5. Koffing Class: Restores HP “a little bit.” Pokémon gains “a few” experience points and gets friendlier.
