Method1) Prep the corned beef. If possible, make your own corned beef. It is just plain better than storebought. For pastrami, the flat section of the brisket is favored by many because it makes nice even slices for sandwiches, but I prefer the point section of the brisket because it is fattier, richer, and more tender. It can also be made from flank steak, or leaner cuts, or even from boneless short plate (rib meat). If you are using brisket, one side of the meat will probably have a thick layer of fat on it called the cap. Remove all of the fat cap except about 1/8" and if there is any filmy membrane on the other side, remove it all. That thin layer of fat is important. The process takes about a week.2) Desalinate. Put the corned beef in a pot slightly larger than the meat and cover it with cold water in the fridge for at least 8 hours. This removes excess salt. Trust me, you need to do this or you will be gulping water all night after your meal.3) Rub. Make the rub. Rinse the meat, and while it is damp, apply the rub liberally, about 4 tablespoons per square foot of surface, and press it into the surface to help it adhere. If there is a thin part of meat, use less rub. Put in the fridge for a minimum of 2 days. Don't wrap it. The rub just sticks to the plastic wrap. Normally I say you do not need to let meats marinate in a rub, but the wait seems to help this particular rub adhere. 4) Fire up. Set up your grill in 2 zones for smoking or set up your smoker. If you can, use a charcoal smoker. It produces a deeper darker crust than any other cooker. Preheat to 225°F. Pick your wood. I don't think it makes a huge difference with all the other flavors banging around in there. My best batch was with cherry wood.5) Cook. Place the meat on the smoker or on the indirect heat side of the grill. If you plan to steam it before serving for maximum tenderness, you only need to smoke it with indirect heat until it reaches the stall at about 150°F. You can wrap in foil and refrigerate for a week if you wish or proceed to the steaming step. The downside is that steam softens the crust. You can skip the steaming and smoke it up to 203°F and have a nice firm smoky bark, but the meat will not be quite as tender. But it will be tender. And delicious. Your call. Try it both ways and pick the method that suits you best.6) Steam (optional). If you want to steam it for maximum tenderness, if you have a bamboo or metal steamer in which the meat will fit, you can use that. If not, you can make a steamer by putting a wire rack in a baking pan. If necessary you can sit the rack on wads of foil to keep it out of the water. Unwrap the meat and put it on the foil in which it was wrapped or the steam will wash off much of the rub. Do not slice the meat first.7) If you made a steamer with a baking pan, cover it with foil. If the pan is steel don't let the foil touch the meat. The salt, the water, the steel, and the aluminum can interact and create electrical charges that can melt the foil! This is a phenomenon called the "lasagna cell" because it happens to lasagna often.8) Put the pan on a burner, turn the heat to medium low, and steam it an hour or two until heated through to 203°F. Add hot water as needed, making sure the pan never dries out. Don't rush this. Take it all the way to 203°F. Note that the crust tends to get soft when you steam. No doubt about it, a hard crust is more appealing. So you can firm the crust by putting it on a hot grill or in the oven or under the broiler for a few minutes. The best crust comes from smoking up to 203°F and skipping the steam. The big puzzlement is how does Katz's retain the hard crust even though they boil the meat just before serving. Dr. Blonder speculates that they pack the meat in so tight that the crust remains hard. I'm skeptical.9) Slicing. Slicing is crucial to maximize tenderness. Look at the meat and notice which way the grain is running. Cut it by hand in thin slices, about 1/8" thick, perpendicular to the grain. If you cut parallel to the grain it will be much chewier. Don't try to slice it with a machine. It will just fall apart.10) Serve. I serve the homemade smoked pastrami on fresh untoasted rye bread. A good brown mustard on both slices and a few shreds of sauerkraut is nice but not necessary. Now this is going to sound weird: It may need a light sprinkling of salt. The soaking process occasionally removes too much. So taste it and if you wish, sprinkle it on lightly. At Katz's they put about 1 pound of meat on each sandwich, and the Carnegie Deli uses even more. That's just too much for me devour without unhinging my jaw. 1/2 to 3/4 pound per sandwich is more than enough for home use. If you want, you can make a Rockin' Pastrami Reuben with sauerkraut, melted swiss, and thousand island or Russian dressing, or beter still, my famous Burger Glop. Reubens were originally made with corned beef, but there's no rule that you can't make one from pastrami. In fact, I highly recommend it.11) Leftovers freeze well and they can be reheated in the microwave or steamed. They can also be made into a killer hash.Ess, bench, sei a mensch!
