Tuna tartar variation with Jalapeno pepper 鮪のなめろうハロペニョペッパー入り

This is "a variation on the theme of tuna namerou 鮪のなめろう".  I think two of our favorite ways  to enjoy the block of low-quality but readily available frozen yellowfin tuna are "namerou" and "negitoro" ネギトロ. I could have made this tuna namerou as before but the limitation of what I had in terms of the ingredients forced me to make some changes. I also borrowed some ideas from making "negitro".  I garnished it with thin slices of Jalapeno pepper hinting at  what this namerou contains.

These two servings are made from a half of the tuna block but it turned out to be  quite a lot (for us, at least). 

Making this is rather simple. This time, modifications included using Vidalia onion (in stead of scallion) and Jalapeno pepper.  I cut the tuna into small cubes, added finely chopped, deseeded, and deveined Jalapeno pepper (half of large one), finely chopped Vidalia onion (half of medium sized) and miso (I added a bit more later after I tasted it). In addition, I added the Spanish olive oil we really like. As I "hit" or "tataku" 叩くit with my heavy chef's knife, I gradually added the olive oil to incorporate (instead of using mayonnaise when making negitoro) until it became the pasty consistency and still some small chunks are remaining. I also add a little bit more olive oil on the top as I served this.

Although we started the evening with a Napa cab, we switched to cold sake (We happened to have "Dassai" 獺祭 daiginjo 大吟醸 from Yamaguchi 山口県 prefecture). We thought the addition of Jalapeno to this dish was a good one. It added a fresh pepper taste without adding any heat (since I removed the veins and seeds). Although quite subtle, the addition of olive oil also added to the  unctuous texture.  The amount of miso was just right and we could really taste nice miso flavors with nutty-saltiness. I had a few more dishes planned but at this point, we were quite full.
