16. If a baker, a copy of How to make Artisan Bread in 5 minutes
(or something like that).
I agree with a good knife, though I don't know how good a one you can get for $30. But the book on artisan bread is great. I did it all last year. No mixer, no kneading, no formed baking pans, 15 minutes to set up the dough originally, then when you want to use it, just 5 minutes in the morning (plus baking time).
If I'm up to it (have medical issues) I'll do it again this winter.
