Putting ingredients inline is interesting. I think I actually see the sense in it. As a reader, I want the ingredients list at the top, but as a writer, I'll think about ingredients as I write the instructions. So, doing it this way potentially saves on jumping back and forth between the instructions and the list, which almost feels like boilerplate.

However, if you want to make shopping list annotations, then you're doing that extra work anyway. In a separate file? It'd be cool if the spec allowed for doing an ingredients list with annotations at the top of the recipe if the writer so chooses. The current syntax works, but not for all people/scenarios.

How would I do recipes with sections? For instance: https://www.kingarthurbaking.com/recipes/fast-summer-berry-p...

Note the ingredient sections; crust, filling, topping. Note the step numbers. Note the link to another recipe. Note the step section titles that are represented here in bold and which don't perfectly match with the ingredient sections. Note the footnotes at the end.

Not sure how I'd do most of those things with this markdown spec.
