Liver Onions and Vinegar

Liver is a superfood with many important nutrients. If eating liver seems a little bit too much, don’t worry, this recipe makes it healthier, easier and more enjoyable than you think.


  • 500 grams of fresh calf’s (or Pork) liver
  • 2 to 4 tablespoons butter, as desired
  • 2 large Spanish onions, sliced lengthwise into thin strips
  • Salt and pepper, as desired
  • 1 tablespoon vinegar, (Black, Balsamic, Apple Cider)
  • Flour for dredging, seasoned with salt and pepper
  • 2 to 4 tablespoons clarified butter for frying
  • 2 tablespoons chopped parsley


  • Trim liver of veins and membranes. Cut on the diagonal into wide,  slices.
  • Melt the butter in a large skillet. Fry the onions in the butter over medium heat, stirring often, until nicely browned, 10 to 15 minutes. Season to taste with salt, pepper and vinegar. Set aside.
  • Dredge liver pieces with seasoned flour, and shake off excess. In a second large skillet, melt the clarified butter over high heat, and when very hot, drop in the liver pieces, a few at a time.
  • Fry 30 seconds or so on each side. Remove to a serving dish. Liver should still be raw in the center.
  • When all liver pieces have been fried, place the onions in the skillet containing the liver juices and reheat the onions thoroughly, stirring often. Add the liver to the onions, toss briefly to heat through, and turn out onto the serving dish.
  • Sprinkle with chopped parsley.

Benefits of Liver

In addition to a high concentration of vitamin A, the liver is high in calcium, phosphorus, selenium, the vitamin B complex, and iron. The liver is a storage organ for many important nutrients (vitamins A, D, E, K, B12 and folic acid, and minerals such as copper and iron).

Liver according to Traditional Chinese Medicine.

According to the Doctrine of Signatures, we should eat liver to nourish our own liver. According to TCM, eating liver greatly nourishes Liver Blood (TCM blood), which is closely associated with the menstrual cycle and helps to rebalance any hormonal imbalance. In this recipe we also use vinegar which is sour in nature and helps to promote the smooth flow of Liver Qi, when it is blocked or stagnating.

Regarding toxins! The liver’s function is to neutralize toxins (such as drugs, poisons, and chemical agents), it does not store these toxins. Toxins that the body cannot eliminate are likely to accumulate, elsewhere in the body’s fatty tissues and nervous systems.

I recommend only buying liver from reliable sources, where the animal is organic or grass fed.
