First off the packaging of this naval was the best I've seen from anywhere that I've ordered meat
I make a good bit of pastrami, and I've made it with USDA Choice brisket, USDA Prime brisket, US produced Wagyu and even Picanha. They've all been excellent, but I have to say the wagyu brisket was the best texture (melt in your mouth like butter), so that's what I'm comparing this pastrami to that I made with the BMS 7+ wagyu naval.
I used my exact same brine and brined it for 4 weeks. I rinsed it, dried it and rubbed it with my same dry rub. I smoked it with the same wood (macadamia wood) and used my same smoking technique wrapping it at between 165˚ and 170˚ in pink butcher paper. I smoked it to an internal temperature of 190˚. I then placed it in a cooler and allowed it to rest over night.
It definitely has the "wiggle" and boy is it juicy. I thought it was going to be too much fat but it isn't at all. It went in the smoker at 13.6 pounds and came out just under 6.5 pounds after I cut some off for a sample, so a lot of the fat rendered out. I get a similar weight loss with brisket, especially wagyu brisket.
The flavor is similar to the pastrami I've made with brisket, but very different at the same time. Honestly, I'm not sure which I like best. I'll have to make some rye bread and a few sandwiches in order to make up my mind. The naval is excellent and very moist and tender.
