Tips for Perfect Seafood Cassolette
Use fresh seafood when possible:
Fresh seafood gives the best flavor and texture.
Do not overcook seafood:
Seafood cooks quickly and becomes rubbery if cooked too long.
Dry seafood before cooking:
Removing excess moisture helps create better texture.
Use a gentle simmer:
High heat can cause the cream sauce to separate.
Serve immediately:
This dish is best enjoyed hot straight from the oven.
