4 strips slab bacon, cut 1/8-inch thick and about an inch wide, or 4 strips lightly smoked bacon
4 beef tournedos, cut 1-inch thick, about 5 oz. each
16 fresh sage leaves
coarse salt and freshly ground black pepper
Place the bacon in a saucepan with 4 cups cold water, bring to a simmer, and blanch for 5 minutes. Drain and pat dry with paper towels.
Pat the tournedos dry. Wrap a strip of bacon around the circumference of each, evenly spacing 4 sage leaves in each bundle. Tie with kitchen string.
Heat a chapa or large cast-iron skillet over high heat until it starts to smoke and a drop of water sizzles on the surface. Sprinkle the tournedos with salt and pepper and stand them on their sides on the hot surface, so that the bacon is in contact with the hot pan. Cook, without moving them, for 1 1/2 to 2 minutes, until the bacon is well charred. Rotate the tournedos a quarter turn and cook until the bacon is crisped, then repeat two more times so the bacon is nicely crisped all around. Turn the tournedos to their flat sides and cook for 2 to 3 minutes on each side for medium-rare. Transfer to a platter and let rest for 3 minutes.
Remove the string, and serve the steak.
