Common Questions
Is sablefish the same as black cod?
Yes. Sablefish is often sold as black cod. It is not true cod, but it has a similarly mild flavor with a much richer, buttery texture.
Can I use salmon or cod instead?
You can. Salmon works well with this glaze and will cook a little faster depending on thickness. True cod is leaner, so reduce broiler time and consider brushing with a little extra oil to help keep it moist.
How long should I marinate sablefish in miso?
Anywhere from 30 minutes to 6 hours. Longer gives deeper flavor, but even a short marinate still tastes great. Overnight can start to change the texture (it can firm up a bit), especially with thinner fillets or a saltier miso, so I usually cap it at 6 hours for the best balance.
Why is my miso glaze burning before the fish cooks?
Two common culprits: the rack is too close to the broiler, or there is excess sugary marinade pooling on the pan. Move the rack down one level and wipe off heavy marinade before broiling, then brush a thin layer on top.
How do I know it is done?
Look for opaque sides and gentle flaking. For a silky center, aim for about 130°F to 135°F, and let it carry over as it rests. For firmer fish, take it to 140°F. Food safety note: the FDA recommends 145°F for fish, so cook to the temperature that feels right for you.
Can I swap the miso?
Yes. White miso is mild and slightly sweet. Yellow miso is a bit deeper and usually a touch saltier, so you may want to reduce soy sauce by 1 teaspoon. Red miso is bold and saltier; use it if you love a stronger punch, but consider cutting the soy sauce by 1 to 2 teaspoons and tasting the glaze before you use it.
High broil or low broil?
Use high broil if you have it, but keep an eye on the caramelization. Broilers vary a lot. If it is browning too fast, drop the rack down one level or switch to low broil and add a minute or two.
