Mayo-Yaki Baked Cod In Foil With Lemon

Mayo-Yaki Baked Cod In Foil With Lemon Food & Recipes

Baked cod in foil is my favorite easy, quick, and absolutely delicious way to cook fish, especially cod, halibut, and salmon.

This cooking method is very popular in Japanese home cooking-called Hoil (means aluminum foil,) Yaki (means grilling).

Especially for someone that doesn’t have a great fondness for cooking, this recipe will be perfect!

Also, it can be a fancy dinner when adding a variety of colorful veggies!

I make it at least twice a month since my husband started trying to change his diet.

He doesn’t like fishy fish, but he absolutely loves this dish all the time. Read carefully my Japanese cooking tip to remove the fishy taste from the fish.

Does Mayo Go Well With Fish?

Originally, in the birthplaces of mayonnaise such as Menorca, Mayonnaise has been widely used not only for salads but also for meat and seafood since ancient times.

The animal protein in seafood and mayonnaise (eggs) goes well together, and also vinegar taste in Mayonnaise helps reduce the greasy taste.

Also, Mayyonaise is made by emulsifying, it also can help to reduce the fishy taste while adding rich creamy flavor.

And no need to worry about your fish tasting like mayonnaise, moreover, it enhances the rich creamy savory flavor in the dish.

Why Japanese Mayonnaise?

Especially to use Mayonnaise for a seafood dish, I highly recommend using Japanese mayonnaise which uses only egg yolks.

As I said, animal protein in seafood and egg yokes (also animal protein) combines well and brings savory flavor to the dish.

According to Kewpie Corporation, Kewpie mayonnaise is used with about twice as much egg yolk as American mayonnaise, in fact, using only egg yolks gives a creamy and mellow savory taste.

Moreover, a unique cap of the Kewpie Mayonnaise bottle tube is easy to drizzle, without making a mess on the tube or your hand.

Salt Fish To Remove The Fishy Taste

Basically, you should not wash raw fish in your sink, besides, it is not necessary to rinse packaged fish already gutted and scaled.

For another reason, rinsing raw fish causes watery and easy to take apart while cooking.

The important keys to eating non-fishy fish, get fresh fish and eat it in the day ideally.

Sprinkle a pinch of salt on the fish fillets.

Due to osmotic pressure, the substance that causes the fishy taste will come out.

Tap dry all moisture from the fish with kitchen paper thoughtfully.

Change the paper a few times since all moisture causes the fishy taste.

However, do not leave the fish with salt for a long time, which also gets rid of rich flavor.

The mild fishy taste fish such as cod, halibut, mahi-mahi will be salted for 10 minutes, and the fish that have strong taste such as mackerel, sardines will be for 20-30 minutes.

Sauce & Seasonings

You can use butter for spreading on the foil, additionally, put 1 tbsp of butter on the fish.

I recommend my Authentic Teriyaki sauce top with it to twist flavor.

Also, you can find Asian fusion flavors from my Japanese-style sauce & dressing recipes.

Also, you can use Japanese tartar sauce instead of drizzle Mayo.
