Traditional Midsummer fare is served buffet-style, similar to the food served at Christmas or Easter, with a focus on summer crops such as new potatoes, radishes and strawberries, rather than winter vegetables like cabbage and kale. 

Midsummer is always celebrated on the Friday closest to the summer solstice, which falls on June 24th this year. It’s not technically a public holiday, but it is listed as a day off in Sweden’s Annual Leave law, so you will probably have the day off if you ordinarily work standard hours on weekdays.

Here’s what you’re likely to see at a Midsummer celebration, as well as how you can make it yourself.

Herring

It wouldn’t be a proper Swedish celebration without pickled herring or sill. In many families, one member of the family (often a grandmother) is tasked with preparing sill for the Midsummer meal weeks in advance.

If you’re based in Sweden, you can buy herring in the supermarket, although most will say that homemade pickled herring is superior. Vegetarian or vegan pickled herring substitutes such as svill (made from mushrooms) and tofusill (made from tofu) are also commercially available.

If you are planning on making your own pickled herring for Midsummer, you have a few options. Either you can buy ready-salted herring fillets in the supermarket which can be pickled straight away, or you will have to buy fresh herring fillets which you salt yourself – the latter option can take up to two weeks though, so you’ll have to save that for next year if you want to try doing it yourself.

You can also make your own vegetarian options: try pickling aubergine, courgette or tofu. Most recipes will take at least two days, with the herring or alternative of choice needing to marinate overnight before serving, so you’ll have to start it today if you want to have it on the table for Friday.

Here is a selection of pickled herring recipes in English.

Herring is usually served alongside bread or crispbread, cheese and butter, referred to as an S.O.S. (sill, ost och smör), so make sure you pick up some bread and hard mature cheese such as västerbottensost if you want to recreate this dish.

Summer crops

Some early varieties of potato are ready just in time for Midsummer, making them a feature on the Midsummer table. New potatoes, färskpotatis (“fresh potatoes”) in Swedish, are delicious by themselves, so you’ll often see them just served boiled, cooled, and sprinkled with dill.

Radishes are also a popular feature on the Midsummer table as they are ready at this time of year, although it can be difficult to find Swedish radishes in the shops. They’re often served raw, perhaps with a dip of sour cream or gräddfil on the side.

Finally on the summer crops front, strawberries are the crowning glory of the Midsummer table, with pundits closely monitoring the harvest in the weeks leading up to the holiday. Strawberries and cream are a classic combination, either served as-is or in some sort of strawberry tart or cake.

Salmon

Most Midsummer buffets will feature at least two sorts of salmon, one is often a baked side of salmon. Along with baked salmon, you’re likely to find smoked salmon and/or gravad lax (literally “buried salmon”, preserved in salt, sugar and often dill) alongside hovmästarsås, a mustard and dill sauce which is also served at Christmas.

If you don’t eat fish, you can make a vegetarian or vegan version of gravad lax from carrots. This is usually referred to as gravad morot. Here’s a recipe (in Swedish) from the book Vegansk husmanskost by Gustav Johansson. Again, it needs to be marinated overnight, so you’ll need to start this off today if you want to eat it at Midsummer.

Eggs

Although not quite as important at Midsummer as they are at Easter, eggs are another mainstay of a Midsummer buffet.

You’ll often see them served simply hardboiled and cut in half, or potentially topped with mayonnaise, prawns and cod roe, known as kaviar in Swedish. This is sold in small glass jars in the fridge section of the supermarket, and can be orange or black – and is not the same as Kalles kaviar, sold in blue tubes, which is much saltier.

To make these vegetarian, you can leave out the prawns and use a vegetarian version of kaviar made from seaweed. Look for tångkaviar, which may be in the fish section of the supermarket, or the vegetarian section, if your supermarket has one of these.

If you live outside Sweden, you may be able to source tångkaviar in the food market at your local Ikea.

For a vegan option, try sliced tofu topped with vegan mayonnaise (spiked with black salt, if you can get hold of it, which will give it an eggy flavour). Top with tångkaviar and a sprig of dill and you’re good to go.

Snaps

Finally, don’t forget the snaps. Midsummer is the booziest holiday of the year, with Swedes taking breaks throughout the meal to drink nubbar (small bottles of flavoured snaps or akvavit) and sing snapsvisor (drinking songs).

• Snaps: How did an extremely strong alcoholic drink come to define Swedish Midsummer?

Make sure you eat a lot of food to soak up all that alcohol, and you’re certain to have a great Midsummer – maybe grab a couple of frozen pizzas for the next day, while you’re in the supermarket though, to eat when you’re busy nursing your hangover.
