The next time you see a girl inspecting a food product, ask her how she knows whether it's any good or how she will use it to make something worthwhile out of it. (Basically, ask her about whatever it is that's captured her interest in whatever public place.) Lead off with a complement if it's suitable. Don't complement her looks or anything; complement her taste, her ability, or whatever it is that's apparent in what she's doing at that moment.

Let her talk, prompt her along, resist the temptation to take over the conversation (in your head, keep telling yourself to shut up and let her talk), and at the end of it ask her if she'd care to meet up sometime to talk about cooking (or whatever she ends up talking about at that moment)—because, you know, you want to learn more about what interests her.
