Herring is both healthy and delicious!

We love herring in our family, and our daughter Ellen is also quite fond of them. Especially mustard herring which is pickled herring in mustard sauce.

We can buy them ready-made in the supermarket here in Denmark and also in Sweden and Norway I think. They are absolutely excellent, but there is nothing that beats a batch of homemade mustard herring.

So when you need to make some extra good food, or for Christmas or Easter, they must be homemade.

For Christmas lunch or Easter lunch, herring is a must in Denmark. We love to serve pickled herring in mustard sauce, because they just taste good, and most people like them.

Fortunately, they are easy to make yourself, if you buy marinated herring, then only the dressing they are in needs to be made.

Of course, there must be mustard in, and we use a mixture of different kinds of mustard to get the right taste. You can use the kind of mustard that you like best.

In addition, capers, dill, and red onion must be added. This helps to give the herrings a good taste and makes the dressing extra delicious.

Ingredient notes

Marinated (pickled) herring – You can buy whole marinated herring fillets in most supermarkets in Denmark. Then you can cut them yourself to the size that suits you.

Mustard – Mustard is of course needed when we make mustard herring. We use a mixture of sweet mustard, Dijon mustard, and whole grain mustard. Then we get a little sweetness, strength, and the delicious acidic mustard grains.

Red onion – Onions and herring just taste great together. We use red onion as it is not quite as sharp in taste as regular onions. You can also use shallots instead if you do not have red onions. Half of the onion is finely chopped and comes in the dressing, while the other half is used for garnishing on top of the herrings.

Capers – Capers in the dressing give an acidic note to the otherwise slightly fat herring. It’s super delicious, but you can omit it if you don’t like capers, or you can replace them with chopped gherkins.

Dill – Dill, and fish are great together. Alternatively, you can use chives or cress, but we like it best with dill.

Sour cream – Use the one you like best. Here the sour cream is at 18% fat.
