When it comes to Curry, there are 151 Possible Curry Combinations with the ingredients and berries you can obtain in the game. Each combination will be registered into your Curry Dex, and with it, you can check to see your highest tasting rating for each curry you have made (as well as the score you received for the first time you made a certain curry). The size of each curry will also depend what Pokemon you have, with larger Pokemon needing more curry than smaller ones, and there are three sizes of each curry to collect for your Curry Dex.
Unfortunately, you won't be able to make every Curry unless you trade with someone of the opposite version, as Bob's Food Tin is exclusive to ]Pokemon Sword and Bach's Food Tin is exclusive to Pokemon Shield. But if you do complete the entire Curry Dex, you can receive the Golden Cooking Utensils from the Camping Guru in Hammerlocke Hills (he'll also reward you along the way when reaching other certain milestones in terms of entries in the Curry Dex).
