I have a question about the recipe "Roasted Salmon with a Cheat's Vietnamese Caramel Sauce" from Kristin. Would a white butterfish work as well as salmon?

Hi Melissa! You could likely substitute butterfish, but remember that there are some health risks associated with butterfish (you aren't supposed to eat more than 6 oz at a time because you can get keriorrhea). Other white flaky fishes would work well also, like halibut, tilapia, or snapper.

The sauce might take over a milder flavored fish. That doesn't mean it wouldn't work, but it would be very different. Bluefish would be a more similar substitute--or tuna.

I think the most typical Vietnamese preparation would be with catfish, so Kristin's salmon was itself a culinary stretch.
(By the way--there are lots of different fish called butterfish. The one that Liza's Kitchen mentions is also as escolar or white tuna, and I suspect she guessed right that it was the one you meant. But that's the only one that bothers some digestive systems--I'd hate to sound an alarm on all the "butterfish.")
