Custom Foods and Recipes include the option of assigning a Brand and Classification. It is similar to how the CalorieKing food database is categorized using brands and food categories.
An example of a brand is a restaurant name or product manufacturer label. Or, you might choose to brand custom recipes as Homemade so that all homemade recipes appear together in a diary food search. An example of a classification is a food category (e.g. beverage, pasta, salad, etc).
You could also use the brand or classification option to provide the source of the recipe - cookbook, website, magazine, "grandma", etc. Think of it as a filing system for your custom foods and recipes.
