As long as the level reaches a certain level, all kinds of recipes can be unlocked, so the level is very important, but the things that can be unlocked are limited.
Step 2 make your own food
You can also cook by yourself and mix them casually, which may unlock new recipes, but there will still be more dark dishes.
3. Adventure mission
When encountering an adventure task and completing it, some rewards are recipes, so the rest of the tasks are triggered.
4. Identity storage
Buy recipes directly in the identity store, but you need to consume identity points, so you should do more identity tasks.
