Use the Restore List button at the top of the Shopping List to restore your list to its original condition. This will do two things:

  1. This will restore all ingredients that have been checked off of your shopping list.
  2. You will also have the option to remove all manually added items on your list.

Items that you have manually added to your list will remain on your list indefinitely until they are either removed individually or the Restore List button is used.
