Smoked lamb shoulder tostadas topped with zesty pickled veggies, creamy Mexican crema, all on a crunchy tortilla making a seriously delicious symphony of flavors in every bite.
Prep and season the lamb shoulder (the day before cooking if possible). Trim off excess fat, score the fat cap in a cross-hatch pattern, and tightly tie the boneless shoulder together with butcher twine. Drizzle on some oil, then liberally season the entire surface of the meat with kosher salt. Cover and refrigerate overnight.
Make the pickled veggies (8 to 24 hours ahead of time)
Make the pickle brine by combining the water, vinegar, salt and sugar in a small saucepan over medium heat. Whisk to dissolve, then remove from the heat.
Place the veggies in mason jars. Carefully pour the pickling liquid into the jars, completely submerging the vegetables. Let them sit out on the counter for 1 hour to cool, then cover tightly and place in the refrigerator for 8 hours to pickle, or longer for more flavor.
To Smoke the Lamb
Remove the lamb shoulder from the refrigerator 1 hour before smoking. Insert a remote probe thermometer into the thickest part of the meat.
Set up your smoker according to the manufacturer's instructions for indirect heat cooking and preheat to 225° F.
Place the lamb shoulder fat side down in the smoker and close the lid.
Begin checking the temperature after 3 hours. When it reaches 165° F, wrap tightly with aluminum foil or butcher paper, after about 4 to 6 hours of cooking. Then place it back in the smoker (or in the oven). *For faster cooking, you can increase the temperature to 275 to 300° F to finish cooking more quickly once it is wrapped.
For dice(able) texture, remove from the heat between 190 to 195° F. For shreddable texture, remove at 203 to 205° F.
Rest for 30 minutes to 1 hour, then dice or shred.
Crisp up the lamb: Heat a cast iron skillet over medium-high heat and crisp up the pulled or diced lamb shoulder for 2 to 3 minutes, stirring a few times.
Assemble the tostadas with your sauce and toppings. Enjoy!
Notes
The lamb can be made the day before. Just heat up in a skillet for the tostadas.
Place a water drip pan in the smoker to create a more humid environment, which helps attract smoke and keep the meat juicy.
Spritz if you wish. Use a 50:50 ratio of water and cider vinegar (or apple cider) in a spray bottle and spray it on the lamb shoulder a few times after the first two hours to help keep it moist and attract smoke.
Cook time: figure 2 to 2 1/2 hours per pound, but it's always best to cook to temperature rather than time. **The USDA recommends a minimum internal temperature of 145 °F (62.8 °C) with a 3-minute rest.
