Chicken Livers With Caramelized Onions and Mushrooms

Preparation

1. Step 1

   Put onions in a large skillet over medium heat. Cover and cook, stirring infrequently, until onions are dry and almost sticking to pan, about 20 minutes.

2. Step 2

   Stir in a tablespoon of oil or butter and a large pinch of salt and a few grindings of black pepper, add rosemary and turn heat down to medium-low. Add mushrooms and cook, stirring occasionally, until mushrooms release their liquid and it evaporates, about 15 minutes more. Remove vegetables from pan; set aside.

3. Step 3

   Wipe pan with a paper towel, put it over medium-high heat and add remaining oil or butter. When oil is hot or foam from butter has subsided, add chicken livers. Keep heat high and cook livers quickly, turning them until brown and crisp on both sides but still pink on inside, about 3 or 4 minutes total. Remove from pan.

4. Step 4

   Return vegetables to pan along with vinegar and 2 or 3 tablespoons water, just enough to deglaze; stir well to combine and serve with livers and crusty bread, or on toast.
