Galley allows you to create dietary flags, in addition to the flags that automatically exist in the account.
To create a new dietary flag, go into the Ingredients catalog and click View Dietary Flags. You will then be directed to a catalog of all dietary flags in the account.
To create a new dietary flag, click the +, enter the title of the dietary flag, and click Create.
After the flag is created, you will then be able to link the link your new custom flag to ingredients. This is done exactly like the other dietary flags, by searching the Dietary Flags dropdown on a given ingredient's page.
Your new dietary flag will then appear in the Custom Flags section of the recipes where the associated ingredient(s) are used.
Note: these custom dietary flags will not appear in the Allergens section of your nutrition labels.
