This was how I was trying to do it, although I didn't know about the milk trick (does it really make that much difference?) I do have a lb of grassfed liver in my freezer right now, but I've decided that I just don't enjoy it. I don't want to have to choke down a meal once a week that I dislike, so my new plan is to stock up on some grass fed liverwurst from US Wellness and just eat a bit of that every week.
Maybe I will give it one more try soaked in milk this week to see if it makes a difference, but honestly I think part of it is psycho-somatic - I just get a little creeped out about eating organ meats in general. Liverwurst doesn't give me the same willies, maybe because I ate the Oscar Meyer stuff on sandwiches a lot as a kid so I'm used to the flavor and texture.
