I am glad you like the recipe, it is delicious. I have never prepared this a day ahead. I would think it would be fine, just make sure your fish is completely thawed if using frozen. Let me know if you try it, I will be interested to hear how it works for you. Thanks for sharing!

quick question, is it ok to prep the day before and leave in the fridge on the plastic wrap to just the day after cook at dinner, please advice. btw. delicious recipe

I am pleased that you gave this dish a try. Haddock sounds like a nice choice. I have not had the issue of excess moisture but have never held them long or used something other than cod. Sounds like your fish might have been a little wet, perhaps allowing the fish to sit on a paper towel for a while before rolling might help? I hope you will try this one again and thanks for your comment.

This is a dish that requires some practice. It is definitely important to get the potatoes super thin. I let the prepared packets sit in the fridge more than an hour and I think the potatoes and fish created some juice that was not necessarily helpful to a successful cooking experience. I would definitely NOT do this for company until I had mastered the techniques. Delicious anyway. I used haddock.
