Preparation
Step 1
Pat the steaks dry and rub them with the salt, chipotle powder, and cilantro. Refrigerate the steaks, uncovered, for at least 1 hour, or up to 8 hours.
To make the mustard butter, mash together the butter with the mustard powder and the Dijon. Form it into two mounds and chill on a plastic wrap–lined plate.
Heat a little oil or clarified butter in a grill pan or cast-iron skillet and cook the steaks over high heat, being sure to get a good sear on each side. For rare steaks, cook 5 to 7 minutes total on both sides, or aller-retour (“to go and return”).
Remove the steaks from the pan and put on plates. Top each steak with a knob of the mustard butter and some ground black pepper and serve with a big pile of frites.
