I have a batch of Teriyaki Jerky in the fridge right now that will be processed (
dehydrator) today.
I used 3/4 of a cup of Kiikkoman Teriyaki Marinade and Sauce as the base, then added the powdered and ground seasonings.
1.88 pounds of Beef top round roast, hand sliced (cordless, 10", cimiter knife).
It's been marinading overnight in a 1 gallon plastic bag with the air removed, and massaged periodically.
So there is an example of a lesser amount of marinade being used for 1.88 pounds of meat.
(Probably 1.5 pounds after the dogs trimmings.... ;) )
The recipe called for 1/2 cup of the marinade per pound of meat. 1 Gallon Ziploc baggies can be your friend.
Something to note here. I made a double batch of Bear's marinade for Salmon once. Danged if the stuff I was saving didn't go bad on me. :( So I make it as needed now.
Fresh marinade for each batch of meat being done. ;)
