okoge" おこげ. As a kid, I remember "okoge" was a good snack. My mother used to make rice in a traditional Japanese pot called "okama" お釜 with a heavy wooden lid when I was a little kid. After the rice is cooked, rice has to be transferred to a wooden vessel called "ohitsu" お櫃 (see the image) leaving a charred crust on the bottom of the pot. This crust is called "okoge" and it was nicely crunchy and flavorful. With just a small amount of miso, you could have the entire meal just eating "okoge".
This dish is trying to recreate this "okoge" with some Italian twists. I must have seen it in one of the many Japanese drinking food cook books that I have. I did not find or check the original recipe this time and I may have changed something but it is a simple preparation of leftover rice rather than a recipe.
I use leftover frozen rice (about one cup for two servings). I defrost it in a microwave oven so that rice grain can be separated but still cold. I add the rice and 1-2 tbs of chicken broth (my usual Swanson no-fat, low-sodium) to a small pan on a medium flame and mix them with a silicon spatula until the rice gets heated up and absorbs the broth and becomes somewhat sticky. Remove from the heat and place the rice in a metal bowl and let it cool down a bit. I then grate a good amount of Parmigiano-Reggiano cheese (about 3 tbs but the amount is arbitrary) and mix it in the rice.
