Grilled Shrimp with Honey-Ginger Barbecue Sauce

"Of all the ways to prepare shrimp, the grill delivers the best flavor. Although unadorned "shrimp on the barbie" are great, an easily assembled gingery barbecue sauce makes them that much better. You can save time by buying already shelled and deveined shrimp, but our recipe developer, Alexis Touchet, who grew up in shrimp country in southwest Louisiana, thinks shell-on shrimp are better quality. Depending on where you live and what's in your market, you may not have much choice. Freshness trumps all, so don't hesitate to use your nose in deciding which shrimp to buy.
