The glasses could present a recipe as actions needing to be taken in the field of view, instead of as a bulletpoint list in a book. And the glasses could use the video stream from the glasses to improve help an AI may give during cooking.

Then again, I don't see myself using them. I also cook and I'd rather just internalize processes and recipes, and something like this would make it way too easy to just rely on the glasses to "know" everything.
