I hate saying this but until it's done. Invest in a good meat thermometer and test it until it hits your desired doneness. Sometimes it's 12 minutes, other times 16. I aim for an internal temperature of 125 for salmon and 130 for everything else. I use this one
Please don't sear anything that's frozen.

Thanks - I didn�t realize that you thawed the frozen salmon before searing it.
And... I currently lack space for another cast iron pan. We have a square 12� Scanpan with ridges - I�m not sure if it is adequate to function as a cast iron. I use it for making grilled cheese. Our other 12/14� (?) pan is a normal �frying pan�

So you just remove the foiled fish from oven to check the temp? We have an older meat thermometer that works well. I�m satisfied with just checking at the 12 minute mark and then every 3 minutes. Do you use 400 temp? thanks again for your info, esp posting your absolutely favorite way to have frozen fish, because it sounds delicious and I look forward to trying it. I�m going to screenshot and convert to pdf :-)

For tacos, what about grilling your fish? Your Scanpan with the ridges is actually a grill pan it sounds like so if you don't want to use your gas grill you can certainly do it in the scanpan and get some nice grill marks.
When food thaws it lets go of some moisture and if you cook it from a frozen state you are not going to get a good sear on it. If you are cooking it in liquid already such as poached it doesn't matter.
When I cook fish sealed in foil I use the non-stick foil which I love. And you can kind of tell by looking and pushing down with your finger if it is done. If you have an old dial meat thermometer with a thicker probe you might want to get an instant read digital one that has a thinner probe to use for fish and as long as you are buying a new one you can always get one where you leave the probe in the meat/fish/chicken and a little wire sits outside the oven or grill with a display of the temp on it. It is great because you don't have to keep opening the oven or grill to check on things and then having the temp drop each time.

I start with the probe in and run the line out and rest the thermometer on the counter next to the stove. When it dings, it's done. I do cook them at 400.

Ooh - I didn’t realize that the thermometer listed was intended to stay inside the oven while the digital reader could be outside the oven. What genius tech! Thanks :-)

can the cod (fleshy white fish) be used for fish tacos?

I didn't see what thermometer you are referring to but there are several kinds. Some stay inside the oven and usually has a big round dial. I prefer an instant read either with or without the little part that stays outside the oven and shows the temp. Just a regular digital instant read is fine too but you have to open the oven or grill to test the meat.
And yes--cod is very popular for fish tacos.

On cod:

Cod is very common for fish tacos, but it is almost always battered and fried which you don't care for. I much prefer battered fried fish in tacos, but if I'm having grilled fish tacos, I want a firmer fish such as mahi mahi.

my normal fish taco is a thin fish (snapper, sole, Ling cod); I�ll keep in mind that the Costco cod isn�t as great for fish tacos when just sauteed. I�m going to Gus� tomorrow for the �rare� stuff that Safeway lacks, so I�ll probably get some thin fish for fish tacos. Maybe I�ll try a cooking comparison if I feel the energy :-)

I still want to say bra lover. Sorry.

Cod works really well for tacos. I like the texture mixed with some crunchy lettuce/cabbage. I wouldn't grill it but it is more than serviceable out of a foil packet or cooked in a pan.

Wow...you went through all that chicken already.
why not just try the cod and if you don't like it, buy something else next time. Once you get a few toppings on your taco the fish isn't going to be that big of a deal. There doesn't have to be such hard rules.

More fish questions! Just bought swordfish and local red snapper; both wild. I really bought them based on price!
does �fresh wild� still mean it�s previously frozen?
does �wild caught� definitely mean previously frozen?

i use the snapper for my fish taco �base.�

swordfish - I really just want guidance or suggestions. I last consumed swordfish in 2004!!! What are your favorite ways to cook it? I bought a piece, around 11 Oz.

I learn with the best here! I�ll explain that twice Ft has helped me secure a 4-digit cash refund from United. I take ft and all of you ft members extremely seriously. Every post is helpful to read! I greatly appreciate it.

Nothing means previously frozen. Everything was previously frozen. Fresh has no legal connotation.

Grill or pan sear the swordfish like a steak, cook it all the way through. I prefer just salt, pepper, and a finishing sauce. Echoing corky, there aren't too many hard and fast rules around cooking, experimenting is half the fun.

Are you having a party? You have Costco chicken and now cod and swordfish and red snapper? That sounds like a lot of food to consume in the next day or so.
I only grill swordfish. Actually, other than shrimp or scallops I rarely cook any seafood in my house...almost always on the grill. Swordfish is like a steak to me. It is perfect for kabobs or just grilled.
Wild caught refers to the way it was caught not fresh or frozen.
I do think it is possible that the fish you bought were not frozen. Why don't you ask the person who you are buying from? And why do you care?

Thank you - I know you�ve iterated it and I finally googled WP type media about frozen seafood; all complements what you�ve posted. I appreciate this!

everyday is a party!! Fun party of 1 to 3 people.
My Costco chicken 6/pack now has 4 packs in freezer, 1 in fridge, and we cooked 1 last night. Costco frozen wild cod is still in freezer. I bought the 6-Oz swordfish and 1.1-lb of snapper today. The chicken in fridge has a 10/15 date and even Cherries has said that the Costco chicken can last due to its superior packaging.
I�m excited to try the sword fish.
In a couple weeks, it�ll be fun to buy more frozen fish at Costco.
I�m still self-educating about fish; it�s all new to me and I hadn�t thought of it until summer 2020.
you know how directly asking questions hasn�t answered:
1. 2nd date with Veronica?
2. Dna test status
3. Cherries� pizza toppings
4. MIL check

do you really want me to get into more trouble with my questions????
