Bracconiere is right - sharing custom foods and recipes is a Gold feature! You can learn more about our Gold features here: https://cronometer.com/#gold
To add a friend you would like to share custom foods and recipes with, navigate to the Sharing section in the Profile tab. Select Add Friend, then enter in your friend's email address. They will receive an invitation to be your friend. Once they accept, you can search for one another's custom foods and recipes. Use the Custom tab when searching for foods to find them more quickly.
