Slice top round steaks across the grain about 1/4 inch thick. Marinate beef ovenight in liquid smoke add some salt & pepper. Worchester works well too.
Poke toothpicks thru one end of each strip and hang them in your oven so they dangle down. (be sure to put a pan underneath to catch the drippings)
Put the oven on about 150 degrees and in a couple of hours you have beef jerky.
