The Adjustable Servings feature allows your visitors to change the serving size for your recipe and have the plugin automatically recalculate the ingredient quantities for them.
Different display options can be set in the Template Editor.
The serving size changer will automatically affect the ingredient quantities. It is also possible to let other numbers in the recipe adjust with the serving size by using the [adjustable]123[/adjustable] shortcode.
Any number surrounded by that shortcode will automatically adjust with the serving size. In the recipe summary and instructions you can easily add this shortcode by highlighting the number and clicking "Adjustable".
