Lomo al Trapo was an experiment for us. We have never eaten it in a restaurant or made it, so we didn't know exactly what to expect. The Beef Tenderloin is expensive but doesn't have much taste. This is the perfect recipe for it. Surprisingly it isn't Salty although you encase it in Salt. The Beef picks up the barbecue smokey taste and the Chimichurri Sauce brings it all to life. This recipe is a keeper and we will make again for a special occasion.
Lomo al Trapo (Salt-Grilled Beef Tenderloin)
New York Times
Preparing lomo al trapo calls for a resolute attitude at the grill.
Tenderloin is costly, so you must have faith that you are not going to incinerate a prized piece of beef by enshrouding it in a dish towel and committing it to the flames like a sacrificial mummy. In Bogotá, Colombia, this showstopper is often prepared for a Sunday barbecue.
This method, based on a version from the chef Jaime Pesaque of Sapiens restaurant in Lima, Peru, wraps the center-cut beef tenderloin in a salt-covered, wine-soaked towel. The wine infuses the salt and, through it, the meat, which grills in that package directly on red-hot coals. When the blackened bundle is brought to the table, you crack the crust to reveal the cooked tenderloin within and serve it up in thick slices, with chimichurri, horseradish cream or Colombian ají sauce.
INGREDIENTS
Yield:4 to 6 servings
One whole (2-pound) center-cut beef tenderloin
5 pounds charcoal briquets or lump hardwood charcoal
1 cup red wine (any kind)
3 tablespoons Dijon mustard
¼ cup dried herbs (oregano, thyme, rosemary or any
combination of them)
1 teaspoon ground black pepper
2½ cups kosher salt (preferably Diamond Crystal)
PREPARATION
1. One hour before cooking, remove the tenderloin from the
refrigerator and place it on a cutting board or platter so that
the meat comes to room temperature.
2. Prepare a charcoal fire with the charcoal briquets or lump
hardwood charcoal, using a chimney if you have one. You
want all of the charcoal to burn until you have glowing red
coals, about 25 minutes.
3. Meanwhile, pour the red wine into a medium bowl and soak
a clean white cotton dish towel (about 18 by 12 inches) in
the wine. (You will discard the towel after cooking.) Gently
wring the towel out so that it is still soaked but not dripping
wet. Lay the dish towel on a sheet pan with a long side
facing you.
4. Slather the tenderloin with the mustard and sprinkle evenly
with the herbs and pepper.
5. Spread 1½ cups salt over the wine-soaked towel, making
sure that a few inches of salt will extend beyond the
tenderloin so that the meat can be completely encased in
salt when rolled in the towel. Place the tenderloin on the salt
and press the remaining salt on top of the tenderloin. Lift the
bottom long edge of the dish towel up and over the
tenderloin, rolling the tenderloin up in the salt-covered towel.
As you roll, pat the salt onto the meat as needed to
completely encase it, folding the sides of the towel in as you
would when making a burrito.
6. Secure the wrapped tenderloin by tying it with butcher’s
twine or kitchen string, repeating knots every 1 to 1½ inches.
You can do this with a series of butcher’s knots. If you don’t
know the butcher’s knot, simple knots are fine. Any way you
choose is fine.
7. Spread the red-hot coals in the grill to form a bed big enough to cradle the meat. Place the wrapped tenderloin directly on the coals. After 10 minutes, flip it and cook for 7 minutes. Insert an instant-read thermometer through the burnt towel8. into the meat to check the internal temperature. If the
thermometer reads 110 degrees, remove the meat from the
coals. If not, continue to cook to 110 degrees, flipping one
more time if necessary. Set the charred package on a platter
or cutting board and let it rest until the carryover heat raises
the internal temperature to 120 degrees for rare, about 10
minutes.
8. Using a mallet or the back of a chef’s knife, strike the
charred remains of the dish towel so that the salt crust
cracks. Remove the burnt towel and chunks of salt and then
transfer the tenderloin to a clean cutting board. Brush away
any charred bits and salt and cut the tenderloin into 1-inch-
thick slices, or slightly thicker if you prefer. Serve as is, or
with chimichurri, horseradish cream or Colombian ají sauce.
