“Tekka” 鉄火 in Japanese literally means “iron fire” describing red hot iron. When the red meat of tuna sashimi is used in a “maki” roll or “donburi” rice bowl dish, they are called “tekkamaki” 鉄火巻き and “tekkadon” 鉄火丼, respectively. Here, the red tuna sashimi is equated with red hot iron. One weekend, I made this as a lunch.
Again, this is not a recipe per se but just a description of how I assembled the dish.
Tuna: From a pound block of tuna sashimi, I sliced red meat or 赤身 in relatively thin slices like one would use to make nigiri sushi. I smeared on a small amount of real wasabi exactly like I would do to make nigiri sushi.
Sushi rice: Since this was a lunch, I did not make fresh rice. I microwaved frozen rice in a silicon container and added sushi vinegar (from the bottle). After mixing, I put the lid back on the container and let it steep for a few minutes so that the sushi vinegar was nicely absorbed.
I placed the sushi rice in the bowls and placed the tuna sashimi (with wasabi smeared side down). Since I had a nicely ripe avocado, I sliced it and placed next to the tuna. I sprinkled soy sauce on the top and garnished with roasted white sesame and nori strips.
I also made miso soup with wakame, deep fried tofu pouch or abura-age 油揚げ, and scallions. This is a simplest form of this type of dish but very satisfying. A good lunch for any day.
