Black Pepper and Red Pepper Flakes. A small amount of carb from soy sauce.
Very slight smoke with Applewood. 165 F for 10 hours.
Next time I’m asking the butcher to slice the top round so the slices are uniform. Flavor and texture exceeded our expectations. The yield on 4 lbs of beef was 24 oz (1 1/2 lb) or 30%.
I vacuum sealed and froze most of it since it is addictive.
