Ingredient Singular and Plural
See the Ingredient Singular and Plural feature in action
Go to the WP Recipe Maker > Manage > Recipe Fields > Ingredients page and make sure the "Plural" column is enabled at the top. You can then click on the icon to set the plural version of an ingredient.
While setting this, the "Merge" icon (second to the left) can be helpful to merge any existing plural versions into the singular one first.
