Buck's tuna salad is made with dolphin-safe dry-pack albacore tuna, which goes into an electric mixer with mayo, onion, and celery. Because it's in a mixer instead of a food processor, you get flakes of fish and it never turns to mush. There's just enough mayo to hold it together, and the celery and red onion seem insignificant - until you taste. It has the right amount of crunch and onion bite. Like Buck's tuna salad at Whole Foods, this is made in a mixer. Make two cans at once, so the beaters can whir the salad properly. The tuna should not be pureed or pasty, but a little flaky.
