You can help your friend by sending them an assistant.
To do this:
1. Go to TastyMe
2. Select the Friends tab
3. Go to the My Friends tab, or the Favorites tab if you want to help your favorite friends only
4. Use the Help button next to a friend or tap the Help All button to send help to all your friends at once

You can send help to each one of your friends, but no more than once a day.

If you send help, your character will be displayed in your friend's assistants window.
Help you receive from your friends is also displayed in this window.
