Can herring be frozen?

Before pickling yes, after pickling no

Feel free to freeze!

I had one like that once, it was delicious.

Of course

Yes, absolutely. They are just as delicious after defrosting

If you clean them, dry them properly and close them tightly, they will last for several months in perfect condition. Remember to defrost in the fridge or under running water so that they retain all the taste and health values ;)

Yes it can be frozen safely.

Fresh or baked herrings are best for freezing. It is not recommended to freeze with the addition of cream, oil or onions because these products lose their properties as well as taste and appearance. Prepared herrings, e.g. in oil, with or without additives, can be placed in a tightly closed jar and kept up to 2 weeks in the fridge.

Herrings can be frozen only those that are not yet seasoned

Make sure you do

The question turned out to be ill-defined. It's about herring marinated in oil and onion :) Some say that oil and onion don't tolerate freezing well.

Yes you can

You can, but onions can't be stored for too long.

Yes, herring can be frozen without any problem. However, it is worth remembering that after defrosting, their taste and consistency may be slightly different than before freezing. It is best to freeze fresh, unprocessed herring, and after thawing, use them, for example, in salads or fish pastes. It is also worth remembering a few rules for frozen herring to preserve the best quality: Clean, rinse and dry herring before freezing. Pack in airtight containers or cling film, removing air from them. Label the containers with the date of freezing so you don't keep them in the freezer for too long later.
