How to Make It
In a large cast-iron skillet, cook half of the bacon over moderately high heat, turning once, until browned and the edges are crisp, 5 to 7 minutes. Transfer to paper towels. Repeat with the remaining bacon.
In a small bowl, blend the butter with the sherry. Spread it on the baguette bottoms. Top each with 2 slices of bacon, close the sandwiches and serve.
Back bacon includes a portion of both the loin and the belly. It’s available from British butchers and amazon.com, or try a combination of Canadian bacon and thick-cut bacon.
