looking for a good steak marinade

For tougher/cheaper cuts you need an acid and a salt to break down the sinew. Some things you can use or use a mixture of:

Balsamic
Citrus lemon/lime
Soy
Hoisin
Italian Dressing

I like a mix of soy, balsamic, lime, brown sugar, ginger and green onions. Works great with flank steak.

My other trick I use on most steaks, from the toughest all the way up to tenderloin. I fill a spray bottle with balsamic. I spritz the steaks while they're on the grill and they get a nice crust on them from the carmelizing sugar. Yumm

Use the brine from a jar of dill pickles, it has the acid, salt and spices to break down the sinew, it seasons the steak, and it tastes absolutely fabulous! Try different styles of dills for variety. Marinate anywhere from 2-24 hours in a ziplock in the fridge. You will be amazed!!
