You either love them or hate them, there's no middle ground when it comes to oysters. Southern writer Rick Bragg drawls out his change of heart in a memoir dubbed "Your First Oyster." Foodie Robb Walsh chronicles his perfect dozen oyster restaurants from Texas to Florida, including Acadiana oyster shop Dupuy's, in Abbeville. And there's a half dozen oyster recipes, some of them shocking, like the Oysters Rockefeller adaptation by chef Bryan Caswell of Reef, Houston, Tx., which substitutes the flavors of Thai chili and lime pickle for the traditional liquorice taste of Pernod. It's all oysters in the March edition of Garden & Gun.
