When you do this, your friend’s cookbook appears in your Profile, so you can easily see and cook her recipes yourself.
To follow a friend’s cookbook, first go to your friend’s profile. Do this by tapping the magnifying glass at the top of your screen, toggling to people, then typing in your friend’s name.
Once you find your friend, tap on 'Cookbooks'. Tap on the cookbook you want to follow, then tap the “Save” button near the top right corner of your screen.
Done! Now you can go see your friends' cookbook in your Profile.
