Delicious! I made the recipe as directed. The fish was nice and moist and the sauce was great.

Absolutely divine! So moist and tasty, and because of the sauce, the fish didn't dry out and burn around the edges. I'm going to keep making this, because it's just too good to pass up anymore.

I really enjoyed this dish. I changed the serving to 1. I actually had fresh dill so I used that. I did not measure it just chopped a couple of sprigs. The sauce was delicious. So easy to make. I will definitely make this again. Made for Potluck tag.
