FAQ & Expert Tips

Can I use other types of fish for this recipe?

Yes! You can use any firm, white fish like cod or sea bass.

How do I know if halibut is cooked through?

The best way to tell if fish is cooked is to insert a metal cake tester, metal skewer or a small knife into the thickest part of a fish and hold it there for 5 seconds. Pull it out and carefully touch the tip of the tester/skewer or knife to your lower lip, which is very sensitive to temperature. If it feels warm, the fish is cooked through and ready to serve. If the knife is still cold the fish needs more time.
