My dad loves liver and onions, and my mom doesn't, but she loves him and makes it for him all of...
the time, when requested.
Her trick is super fresh liver, sliced thinly. She sautees at least a 1/2 # of thick bacon first, until crisp/tender, then in the fat sears the liver, then carmelizes several onions and puts the liver back in until it is just done, then adds the bacon before serving.
Her biggest trick is that her portion is one tiny piece of liver and mostly all the bacon and lots of onions, while Ken's is more liver and onions and a little bacon. Doncha just love that!!! Oh, and she opens allllll the windows when cooking! (you can tell liver is not my favorite either, except foie gras and the occasional chicken/duck liver pate that is).
