I love this flowchart from Darya Pino's blog Summer Tomato , though it does subscribe to the Michael Pollan five-ingredient rule (which he has since revised in response to food makers bending the rule ). Even if you already know all this stuff, it still makes its point. [ Addendum, 1:20 p.m. P.S.: This chart was intended as a joke, although it's not altogether unhelpful.]
