BEEF JERKY #18

3 lb Rump roast (or similar cut)
1/2 c Light japanese soy sauce
1/4 c Worchestershire sauce
1/4 c White vinegar
1 c Water
1/2 ts Ground ginger
1/4 ts Ground red pepper
1/4 ts Ground black pepper
1 tb Onion powder
1 Clove garlic; smashed

Have the butcher cut your roast in 1/8 inch slice against the grain OR do it
at home. If you don't have good cutlery, have the butcher do it. It won't be
worth it! Cut off the slice of fat on the bottom. Separate the two distinct
sinews. (you can tell, the grain goes one way on one, and the other way on
the other). Trim out the "gristle" that is between them. slice the two
sinews against the grain into 1/8 inch slices. Mix the soya, and remaining
ingredients to make the marinade. Marinade the meat slices for 6 or 8 hours
in the fridge and then bake in the oven, directly on the rack, for 12 hours
at 150 F.
