For the tuna, I used soy sauce, wasabi and perilla as dressing.
For the salmon, I used soy sauce, red pepper paste (from a tube) and dill.
For the sous vide chicken tenderloin, I used soy sauce and yuzu-kosho 柚胡椒 (from a tube) and garnished with sesame seeds.
These three starters borrowed from the concept of "poke" which is getting popular here. Some fast food "poke" chains have even opened up. Instead of our usual cold sake, we started with champagne.
This was among the ones we happened to have on hand. I am not sure when and where I got this one but it is called Philippe Fourrier Cuvée Millésime Brut Champagne 2008. We made an ice bucket to keep the champagne cold. My wife somehow dug up a special cloth/towel we had tucked away somewhere with a representative champagne bottle depicted on it, to absorb the condensation from the champagne ice bucket.
This was vintaged (2008) and had a nice slightly yeasty/beady aroma with subtle melon and green apple taste with fine bubbles and went quite well with this appetizer I prepared.
After this, we had a filet mignon steak, green asparagus and some kind of potato. We switched to 2006 "the Maiden". This was one of the old wines we had stored in our basement. The conditions there, however, are is not really great for the enhancement of wine over time. We were afraid that the wine may have been way past its prime. I carefully decanted it and let it breathe for one hour before serving. There was a definitive brown hue indicating age/oxidization. As it had more contact with air, this wine opened up and we could taste good black fruit, vanilla and chocolate. The tannin was quite mellow. We would have preferred to taste this wine a bit earlier but it did age quite well and went well with our impromptu celebratory steak dinner.
