Frequently Asked Questions
- Can I broil thin trout fillets instead of baking? Baking is best for thin fillets. Broiling can dry them out very quickly.
- How do I know when trout is done? The fish should flake easily with a fork and be just opaque in the center.
- Can I make the sauce ahead of time? The sauce is best made fresh, but you can prep the ingredients ahead for quick cooking.
- What type of wine works best? A dry white wine like Pinot Grigio or Sauvignon Blanc works well.
