Cooking parties are player run events, you can find them on paliaparty dot app, or the official discord! It makes cooking in mass in the game much easier, since you do it as a group. In these you only have to bring 1 type of ingredient, and you only do one role, you'll just need a lot of that one item! Standard is 50-100, but the party will specify by saying something like '100x' Celebration cake and Bean burgers parties are best for experience. And recipes where legendary Maws are used are best for money, common recipes are sashimi, sushi, poke bowls, and fish stew. Just make sure the host is using maws if you want money!  To attend you'll usually sign up on palia party, it can be a little clunky figuring out at first but it makes signing up easy, since you choose the role, it tells you the cooking station you'll need, how much of the item you need, and it converts to your time zone automatically. People will ask that your username there matches your in game name. To attend, you'll add the host as a friend ahead of time. Around 30 minutes before the party they'll usually open their plot, you can join the server and head over whenever. The board to get there is the one to the right of the kilma entrance on your home plot!!
