Freeze the beef for 1 to 2 hours, until firm. Slice against the grain into ¼-inch strips.
Whisk together the water, soy sauce, brown sugar, Worcestershire, garlic, garlic powder, onion powder, pepper, liquid smoke, MSG, and curing salt (if using) until the sugar dissolves.
Combine the beef and marinade in a zip-top bag. Refrigerate for 12 to 24 hours, flipping once.
Drain the strips and pat them dry. Sprinkle with granulated garlic.
Dry in a 170°F oven with the door propped open for 3 to 5 hours, or in a 160°F dehydrator for 4 to 6 hours, until a cooled strip cracks when bent but doesn't snap.
Spread the dried strips on a baking sheet and heat in a 275°F oven until they reach 160°F, about 10 minutes.
Cool completely, blot off any oil, and store in an airtight container.
