Ok, I've tried and failed to make beef liver that doesn't taste like some nasty bullshit. Looking for recommendations if anyone has pulled it off. Crock pot recipes? Stir fry?
If we are talking about liver from older animals, a classic technique to mellow the taste is soaking it in either 1 part milk + 1 part water, or a mixture of water and lemon or apple cider vinegar. You can also brine it instead, something I personally like. I usually trim the membranes and bigger veins and cut it before soaking/brining, cubes or strips for stews or thin slices for frying. Of course you can also brine or soak the whole thing if you prefer but I just like cutting it up before doing so.
Liver really needs salt so you need to find the amount you like on it, this is also where brining really helps.
If we are talking about liver from old animals I sometimes let it soak for as long as a day in the refrigerator in just plain water before brining it for an hour or two, depending on how thick the cuts are. Liver from younger animals usually do not need as much time and an hour or two of soaking/brining tends to do the job, even in plain water if you want to be really cheap and cut it beforehand. Using apple cider vinegar, lemon, or a brine will of course do a lot for flavor and texture.
My favorite way of cooking liver is thin slices (0.4-0.6 in) that are patted dry after soaking, lightly salted and with bit of white pepper, lightly covered in flour, and gently fried in butter, served with some vegetables (things like asparagus, haricot verts, scallions are great for this), potato wedges, and a béarnaise. Otherwise mixing liver together with other meats in a stew can be fantastic as well, I usually mix beef cubes, thinly sliced beef heart and kidney, and strips of liver together with onions, carrots as a base, then add whatever suitable vegetables and mushrooms I have on hand. Rosemary, bay leaves, and a variety of ground pepper corns are my basics for this kind of stew.
For what I have cooked recently, I just pulled a Chicago-style deep dish pizza with a sourdough crust from the oven. Made from base ingredients and my own sourdough starter, kneaded by hand because I just prefer doing it that way.
