We are sorry, the dish assembly system worked with a plate, but since there is a known bug where the ingredient that you add on the plate didn't appear on it, it might be very confusing. But if you proceed to add three right ingredients on a dish it does proceed to transform into a finished plate which you can deliver to customers. After jam rating ends we will release a patch for all known bugs to fix those issues.
Thank you for playing our game, it means a lot for us, especially since you have to download it to play!
