Steven Raichlen's Salt-Crusted Beef Tenderloin Grilled in Cloth (Lomo al Trapo)

Author Notes: This method, traditional to Colombia, combines two genius techniques to great effect: grilling in the coals and salt-crusting. Each does wonders for beef tenderloin, which Raichlen admits is "normally a pretty boring piece of meat." Adapted slightly from Planet Barbecue. (Workman Publishing Company, 2010)Genius Recipes

Serves 1-2

  • 1 center cut piece of beef tenderloin, meticulously trimmed of all fat and silver skin (about 8 inches long and weighing 12 to 16 ounces)
  • 2 cups salt (we used Diamond Crystal kosher salt)
  • 1 tablespoon dried oregano
  • Special equipment: 1 square piece of clean cotton cloth, 16 by 16 inches (an old-fashioned cloth diaper or piece of cotton sheet works well), dipped in cold water and wrung out slightly
  • Special equipment: Twine (optional)
  1. Arrange the cotton cloth on a work surface on the diagonal (like a diamond), so that one corner points down toward you. Spread the salt out on top of the cloth to form a layer 1/4 inch thick that extends to within 1 inch of the edge of the cloth. Sprinkle the oregano evenly over the salt.
  2. Place the beef tenderloin on top of the salt at the far end of the cloth. It should run parallel to the center axis (and to your shoulders). Roll the cloth and salt around the tenderloin, starting in the far corner. The idea is to make a compact roll. Now take the points of cloth at each end of the resulting cylinder and tie them together on top of the tenderloin. Alternately, secure the roll with twine.The idea is to form a tight cylindrical packet. You should do this right before your charcoal or gas grill are ready.
  3. Charcoal grill method: Light the coals in a chimney starter and rake them out into an even layer at the bottom of the grill. You will not need a grill grate. Lay the wrapped tenderloin right on the coals, knot side up. Grill for exactly 9 minutes. Using long handled tongs, gently turn the tenderloin package over and grill for exactly 8 minutes. Do not be alarmed if the cloth burns; it's meant to. In fact, the whole shebang should look about as appetizing as a fire-charred log.
  4. Gas grill method: Preheat your grill as hot as it will go. There is no need to oil the grill grate. Arrange the cloth-wrapped tenderloin on the grate, knot side up. Grill until the bottom is charred black, about 9 minutes. (The grill should be covered.) Using long-handled tongs, urn the package over and grill until the other side is jet black, about 8 minutes.
  5. Use an instant-read thermometer to test the tenderloin for doneness, inserting through the cloth and the salt into the center of the meat. When cooked to rare, the internal temperature will be about 125 degrees F; to medium-rare, 140 to 145 degrees F.
  6. Transfer the charred tenderloin to a metal platter or rimmed sheet pan and let rest for 2 minutes. Lift the tenderloin with tongs and tap it hard with the back of a large, heavy chef's knife. The burnt shell should crack and come off. Using a pastry brush, brush any excess salt off the tenderloin. Transfer the tenderloin to a clean platter, cut it into 2 to 4 pieces and serve at once.

Oh. My. GOODNESS. I made this last night--did a whole tenderloin for a crowd--and it was absolute perfection. I used sprigs of fresh oregano and the flavor they lent to the meat was divine. A wonderful recipe; thank you!

Loved this! My sister lives in Hong Kong and someone did something like this. She told me bout the method and I found this recipe. We did it with fresh rosemary instead. Great method.

Another traditional method involves soaking the cloth in red wine prior to cooking which sounds god as well!

We tried this last night and it turned out beautifully, despite our gas tank running out about 5 minutes into the cooking process which we didn't notice until we went to flip. Just changed the tank and resorted to our meat thermometer! It was beautiful. Wish we would have known to cook a bigger piece of meat in one dish cloth. We separated a three pound tenderloin into three packets and the biggest problem we had was deciding which dish cloths to live without! What a fun dinner party recipe!! :-)

I haven't tried it in an oven, but please let us know if you try it! It would take longer, but it might work well. See gas grilli method above (step 4) for pointers and be sure to keep an eye on the internal temperature (step 5).

I made this last night and have to say it was really good. It gave flavor to a cut of meat that is usually just a textural experience. I used huge branches of oregano from my garden and it infused the meat with a heady flavor.

Could I do this with a pork tenderloin? How would that change the cooking time?

Sorry for the delay, ChefDan. I haven't tried it with a pork tenderloin, but I'd start with half the time and start checking for an internal temperature of 140 degrees F. Let us know if you try it!

This tenderloin was the most amazing piece of beef i ever made. i prepared a much larger piece almost 8 pounds and cooked it on a gas grill on high. The temperature of the grill read 475 degrees. It took the tenderloin 35 minutes to medium rare. Red in the center. It was perfect. I also substituted the oregano for fresh rosemary and the flavor infused beautifully. I will definitely make this again. Thanks for the recipe!

Do you need to use a chimney starter? We have a Big Green Egg and have never used (so therefor purchased) a chimney starter.

If you can get hot coals, you're set!

Should I close the lid when using a charcoal grill? You only mention the lid when using a gas grill.

No need to close the lid on a charcoal grill (we didn't).

I don't like oregano. What other spice would work well?

Miglore

Another commenter mentioned cutting slits in the tenderloin and pushing in sliced garlic, which sounds great. Anchovy could be added that way too. Lots of other herbs or spices could work -- I might try smoked paprika or dried marjoram.

This sounds amazing! Thank you for sharing! Do we wet or dampen the cloth first?

Yes, thanks for asking! Just added a detail that had gone missing to the recipe.

If you wanted to serve 6 people, could you use a slightly larger tenderloin? Or should I just make 2 smaller packets? Thanks!

Miglore

Yes, go ahead and use a slightly larger (longer) piece of tenderloin in one packet -- it shouldn't change the cooking time, but I'd check with an instant read thermometer to be safe. Have fun!

Anybody tried this method with another cut of beef?....I was even thinkingof attemping to roll and tie a boneless ribeye and go from there?...is that crazy?

Miglore

over 1 year ago Kristen Miglore

Kristen is the Senior Editor of Food52

Hey Plantman -- I asked Steven and he thinks rolling a boneless ribeye would work! You just don't want to try it with something smaller like a hanger steak, because it would be harder to control the cooking and with so much more relative surface area would probably get too salty.

Thanks for your reply....I will give it a whirl in a few days and report back!.....

Any chance there's a way to do this on a gas grill?

Yes, it was buried in step 3 -- I just edited the recipe to make it more clear!
