How do you know when cod is cooked through?
Cod is done when it flakes easily with a fork and the flesh is opaque throughout, typically 4-5 minutes per side depending on fillet thickness.
Can you substitute another fish for cod?
Yes. Halibut, flounder, or haddock work well—adjust cooking time based on thickness, as thinner fillets need less time.
What's the purpose of rice flour in the dredge?
Rice flour creates an extra-crispy crust and browns faster than all-purpose flour alone without becoming tough.
Can you make this ahead?
Cook the cod fresh for best texture. You can prepare the lemon butter sauce ahead and reheat gently before serving.
How do you prevent the butter sauce from breaking?
Keep heat moderate and whisk constantly. If it separates, remove from heat and whisk in a splash of lemon juice to emulsify.
