To help you in finding recipes and compiling Shopping Lists, Mangia!  maintains a Pantry, a list of ingredients you have around the house.

In searching for recipes, the Pantry is used when you check the Cook Without Shopping check-box in the Full Recipe Finder. When that box is checked, Mangia!  will list only recipes that can be made with what is shown in your current Pantry.

Also, in a Shopping List there are often some ingredients which are marked with asterisks (‘*’); these are ingredients which are in your Pantry. Using the Shopping List menu, you can select all or some of the asterisked items and delete them from the Shopping List en masse.

About maintaining an accurate Pantry: Naturally, Mangia!  has no way of climbing out of your Macintosh and poking around your kitchen shelves to do it automatically, so Mangia!  does require a little help from you in maintaining an up to date Pantry inventory (but it even helps with that, too—see Pantry Maintenance under the Goodies Help topic).
