You tried to import one or more ingredients from a text file using Copy and Paste. Mangia!  is rather particular about what it expects this text to look like, and it can’t make sense out of one of the lines you imported. It’s now asking you to help out by interpreting the ingredient as you usually do, filling in the text boxes of this dialog.

You actually have three choices here:
• you can specify the ingredient and let Mangia!  continue the process of importing your ingredient list.
• you can skip this ingredient and let Mangia!  continue with the rest of the ingredients. This will get you the maximum amount of information without effort, and you can go back and correct the list later.
• you can cancel the import process entirely and leave the ingredient list of your recipe as it was before. This gives you the opportunity to go back and “clean up” the text and try again.

If you want more details on the requirements for Mangia!  to make sense out of plain text, see the topic Import Recipes under How To.
