I love this marinade and don't often even measure... you know by the smell that it is just right!  In this incarnation, I am marinading some blade steaks from Withrow's Meat Market - amazing!  I cannot say enough stuff about how amazing this place is... I will be writing a rave very soon!
This marinade is gingery and full of garlic punch....  scale back if you wish to not kill the vamps in your area!

Makes enough for 4 good sized steaks...  I have them resting in a dish -- a ziploc works better.  You can actually freeze fresh meat in this marinade for easier and quicker start up as it should rest for about 8 hours...

Steak Marinade

 3/4 cup sunflower oil -- also have used olive oil...  but it is not as heat resistant when grilling the steaks...
1/4 cup Bragg's seasoning
1/4 cup agave syrup (have also used brown sugar with great success)
3 Tbsp  Apple Cider Vinegar...  I use Boates 
2 - 6 cloves of garlic crushed
2 Tbsp of powdered ginger (4 of fresh)
2 tsp of Chinese 5 spice powder

Mix it up and pour it over your steaks...  

Let it rest as long as you can!

Grill as you like!
