Gail, I never had fresh grilled tuna steaks until I moved to Florida. It was an epiphany to me...
that tuna could taste that good. I just associated it with what I had grown up with: mushy, canned tuna (fishy oil and water-packed).
For some reason, I never thought there would be that big of a taste difference, unlike realizing that canned chicken would never taste anything like a whole roasted chicken.
I welcome your husband to our "holy leaping marlin, that's good!" club.
