Black vinegar soy sauce simmered chicken 鶏もも肉の黒酢煮

This is just a variation on what I posted before. This time, I added potatoes, carrot and broccoli and served it like "nitsuke" 煮付け or a Japanese traditional stewed dish.

As I have mentioned before, I simmered/steamed chicken breast in a mixture of black vinegar (Japanese not Chinese variety), mirin and soy sauce which was called Kurosuni 黒酢煮. I expanded this to include chicken wings and then chicken thigh in the same sauce. I was initially discarding the leftover broth after the chicken meat was consumed. Then, instead of discarding the broth every time, I added water (to compensate for any evaporation during cooking) and added more soy sauce, black vinegar and mirin (1:1:1 ratio) and reused the broth. I strained the broth between uses and also started adding slices of ginger root (fresh ginger root for every batch discarding the old spent ones). I also changed the way I cook the chicken. instead of cooking it and eating it the same day, I now cook it but eat it later. For example, on the first day, I cook the chicken parts in the broth, then let it cool down and put it in the refrigerator. The next day or few days later, I reheat it. This multi-day process provides a few benefits. One of them is that the chicken becomes much more flavorful and tender as a result of it's extended bath in the liquid. The other is that I can skim off the excess chicken fat.

The above picture on the left is after an over night in the refrigerator. I remove the chicken fat using a large spoon (of course, if you are so inclined, you could save it and use it as "schmalz".) After removing the fat (on the right), the broth is completely jelled because of the collagen and protein leached into the broth from the chicken--many batches of which were cooked in the broth. This gellee could be used as a dressing by cutting it into small cubes.

To make a complete dish, I have added nagaimo (the sliminess disappears leaving a very nice texture), daikon (I precooked and then finished cooking in the broth), potatoes (I also precooked), and carrot; all worked well.

Today, I microwaved small red potatoes and placed them in the black vinegar sauce with carrot and simmered them for 20 minutes with chicken thighs. I also added steamed broccoli. I served all these with Japanese hot mustard. So, I have been using the simmering broth for at least several months. The flavor is getting better and better. This time I did not remove the bone from the thigh but we could eat this chicken using chop sticks. The meat was succulent, flavorful and fell right off the bone. 

Since the black vinegar is very mild, this dish will go with wine, especially sturdy reds. We had a very reasonably priced (read "cheap") Tempranillo Bodegas Ondarre Reserva Rioja 2004. This is a sort of everyday wine but went well with this dish.
