OUTBACK STEAKHOUSE AHI TUNA GINGER SOY DRESSING AND DIPPING SAUCE COPYCAT RECIPE. I've tweaked the recipe online, use ingredients shown. It's VERY very close and I'm kind of picky!!! Whoot Whoot, my favorite!!! SCORE! That soy sauce by the way is the best. Try finding it at a local Asian market, if not, Amazon.com has it. Enjoy!!!
