Taste test 1 results: back straps soaked in whole milk for 24 hours, then marinated for 24 hours in an olive oil and vinegar base marinade, then butter fried with garlic.
I think it mostly neutralized the gamey taste. Definitely neutralized the smell while cooking. My wife has a hell of a nose, and she was fine with my pan frying it in the kitchen. Still had to serve with sriracha to totally mask the gamey taste, but it went from inedible to edible but not to be served to guests we like. Next up, buttermilk.
