You can view or otherwise utilize any recipe just as it exists in its recipe file, or before you work with it, you can scale the recipe by multiplying its ingredients by a chosen number or by having Mangia!  scale them to serve a particular number of people.

To scale and view a recipe whose title you see in a list, select the recipe title, then choose Show Recipe Scaled... from the Recipes menu. You’ll get a dialog where you can specify whether to scale the recipe by a factor, or scale it to serve some size of group. When you click OK, the Recipe Card will come up, showing the recipe as scaled.

If the Recipe Card is already up, you can scale the recipe shown by selecting Scale Amounts... from the Recipe Card menu.

In either case, if you send the recipe to the Recipe Clipboard, then the Recipe Clipboard window will confirm the scale changes in  its Scaling column.  You can change this scaling at any time by selecting a recipe, then clicking the Set Scale button.

When you’ve scaled a recipe, it is important to remember that you haven’t really changed the recipe as it is stored in its recipe file. You are only temporarily changing the way the recipe is displayed and printed and the way the ingredients appear in the Shopping List. The only way to change a recipe as it is stored in its recipe file is to edit it as described in the Editing Recipes Help topic.
