Is there a connection between this casado and a casamiento? The latter, which describes a "marriage" of rice and beans that have been fried together, is found in many countries in Central America but is especially associated with El Salvador. A good rendition appears on the all-day breakfast platter at the tiny Salvadoran restaurant Viña del Mar.
Casado, "married man," denotes several platters at La Posada. This basic version, which includes grilled beef, ripe plantain, and a fried egg as well as white rice and black beans, is the casado Costarricense ($12) — in the style typical of Costa Rica. (It's a legacy menu item at La Posada, whose current owners are Colombian.) Perhaps the name was inspired by the inevitable marriage, at the table, of two key ingredients, or perhaps by a style of cooking that a man might miss when away from home: When spooned over the rice, those beans revealed red bell pepper and bits of translucent onion, too. The beans, would you believe, were the best part of my casado.
