A few months ago I had an amazingly delicious fish on a sashimi platter... it was pale white and had a texture that seemed smoother than salmon or the other standards, a bit sweeter, too, somehow. Regardless, it was delicious. I asked my waitress and she said it was "white tuna".
Yesterday I entered a sushi restaurant to find--joy of joys!--"white tuna" featured as a special. I ordered it but the waitress just ticked off the box for "albacore" on the standard sushi order sheet. I told her that I wanted the white tuna special, not albacore, but she said white tuna and albacore are the same thing.
The fish that arrived was greyish and didn't have that ethereal smooth texture. It was fishier tasting than what I'd remembered from the previous restaurant. It was not the same thing that I'd had before.
So, are albacore and white tuna the same thing? Was the first fish "white tuna"? What was the second fish? What happened? I am so sad.
