I would define the project as "Learn to make Japanese Food", and the first subproject is "Sushi". So in my project plan I would brainstorm and write possible actions for making sushi. Some of these I can do straightaway, and I could pick one or several as the next actions.
If I were making sushi, my next actions could be:
- Check Youtube for how to make sushi (context Home Computer)
- Buy recipe book for sushi (context Errands)

You mentioned a possible action as "find recipes (multiple locations)"
Try and keep the tasks specific to a specific context. Finding a recipe in a book you are buying is on the Errands context, but finding a recipe in a book you already have at home would be on the Home context. Finding recipes on the internet would be on the Computer context. Note that you could have all three of these on your lists at the same time, it doesn't matter how many actions you have on your list as long as they can all be done next. Buy ingredients requires a recipe first, and is not a next action (unless you already have one).

< 2 minutes to find a recipe? Do you really think so?
