i don't use salt but i do use soy sauce. then i also usually add
worcesterchire sauce, garlic powder and black pepper. i put it all in a big
ziploc bag and let it marinade for 24 hours (if possible), overnight at the
least

alternately i leave out the worcesterchire and use red pepper sauce (hot
sauce).

I slice it very thin and use a Nasco dehydrator.

I don't worry too much about it being ultra-lean because i store it in the
fridge and it's all eaten in a few days, I don't make huge batches to store
for long periods.

You would worry about the fat in that case because it would go rancid but
it's ok if there is a little bit of fat if you are going to eat it ina day
or 2.

Scramled eggs and homemade beef jerky, mmmmmmmmmmmmmm
