How do I butterfly a salmon fillet without it falling apart?
Place the fillet skin-side down on a cutting board. Using a sharp knife, carefully cut horizontally through the thickest part of the fillet, stopping just before you reach the other edge, leaving it connected like a book. Work slowly to avoid cutting through the sides.
Can I prepare the shrimp filling ahead of time?
Yes. Make the filling up to 4 hours ahead, cover, and refrigerate. Stuff the salmon just before cooking for best texture and to prevent the filling from making the salmon soggy.
How do I know when the salmon is cooked through?
The salmon should flake easily with a fork and reach 145°F (63°C) at its thickest point. The flesh should be opaque and no longer translucent.
Can I use frozen shrimp?
Yes, but thaw and pat completely dry first to remove excess moisture. Excess water can make the filling watery and the salmon texture uneven.
What's the best pan for cooking this?
A cast-iron or non-stick skillet works best to prevent sticking and ensure even browning. Avoid crowding; cook one stuffed fillet at a time for best results.
