I have a good one but it is kind of sweet. It really offsets the venison nicely. I really don't measure.
I mix some soy sauce about one glug of the bottle maybe a tablespoon or two??, wine ( can be red or white, doesn't matter) about two glugs of the bottle maybe about 1/2 cup, olive oil maybe around 2 or 3 tablespoons, again I just pour til it looks right, and a couple spoonfuls of honey and two cloves of crushed garlic (more if you like it garlicy). Taste it, should be a nice balance of sweet, acid and salty. If it is too sweet you can tone it down with squirt or two of lemon juice or more wine. Dump this in a ziploc baggie with the steaks and let em sit for anywhere from an hour to several. Slap on grill and yum. If you like spicy you can always add some crushed red pepper flakes to the mix.
