Say hello to the Easter tree.

Actually, it’s not a tree at all but a collection of long willowy twigs with yellow feathers attached. This is the traditional Easter decoration here in Sweden. Easter, or Påsk as it is known, has some, er, “different” traditions associated with it.

If you’re cruising to Sweden or just visiting, knowing how the nation celebrates holidays helps you prepare for the Swedish mentality. (It’s also useful to know how Sweden celebrates Christmas, but that’s another story. Quickly, however, on Christmas Eve, the whole nation — I’m not kidding, all Swedes, those stylish, sleek, sophisticated people — sit down at 3 p.m. to watch Kalle Anka, which are — now take a moment to prepare yourself for this — Donald Duck cartoons. The first time I celebrated a Swedish Christmas, I thought I had landed in Bizarro World. Actually, Christmas in Sweden is very lovely, with the focus on family. Plus, it’s fun, if not a bit strange, to watch the Swedes mimic Donald Duck and friends.)

For Easter, the big day is Saturday (the holiday is known as Påskafton), when people get together for a traditional dinner that typically consists of sill (herring), lax (salmon), deviled eggs topped with Kalles caviar, kottbullar (meatballs), Prinskorv (a small Swedish sausage) and, of course, Påskmust, which is like a cola but made with a secret recipe.

The same food is served for Christmas, by the way, but with a different cola. Julmust is served during Christmas. Some people swear that they prefer Julmust over Påskmust, but here’s a secret: I believe Julmust and Påskmust are made from the same batch, simply relabeled. Temper your protests please.

And of course, no get-together would be complete without schnapps, beer and traditional songs. Sitting around the table, guests sing familiar favorites before toasting one another (skål). There is a whole tradition around skål that I’ll get to in another post.

One of the strangest parts of the Swedish Easter tradition, however, is the Påskkäring, or the Easter witch.

In Sweden and parts of Finland, the tradition of the witch is said to come from the old belief that witches would fly to a mountain in Germany the Thursday before Easter to cavort with Satan. As the witches returned, Swedes would light fires to scare them away, a practice honored today by the bonfires and fireworks across Sweden in the days leading up to Easter.

This year, a record number of “witches” (nearly 3,000) attended a march in Visby, Sweden. And you thought watching Donald Duck was strange. Children also dress in witch costumes and collect candy, kind of like a mini-Halloween.

Sweden is full of traditions, lovely traditions. One that I enjoy quite a lot is fika. What’s fika? Check out the video below.

Today, another challenge: Who are the people in the photo above? There’s a hint in the headline of this post and in the video below.

In a future post, I’m going to tell you how — and where — to fika. Don’t worry. To fika is perfectly acceptable, even preferred.

I’ll also talk about the Swedish language, which I find to be extremely difficult. It’s true that most foreigners have no trouble pronouncing the number six, which is “sex.”

More difficult to say is the number seven, sju. It sounds like little more than exhaling air, but impossible for the non-native Swede to pronounce properly. So that I never have to say sju, I make it a point not to buy seven of anything. Seven tomatoes? No, I’ll take sex instead.

The castle in the earlier post, by the way, is known both as Kronborg Castle and as Elsinore. The town where the castle is situated also is known as Elsinore. But like the castle the town too has another name, Helsingør. See how quickly things can get confusing over here?

The important thing to know is that the castle was the setting for Shakespeare’s famous tragedy Hamlet, Prince of Denmark. Thus, the castle is known also as “Hamlet’s Castle.”

Built in the 1420s and rebuilt more than 150 years later, it is one of the most important Renaissance castles in Northern Europe. On bike rides along the Swedish coast, I look across the strait known as Öresund to Hamlet’s Castle. Seeing it never fails to enchant me.

The strait, by the way, is less than three miles wide and separates Sweden from Denmark. If you’re cruising the Baltic, you’ll likely pass through the strait, which is one of the world’s busiest waterways. Andreas Eriksson, who is the marketing and information manager at the Port of Helsingborg, tells me that roughly 90,000 ships pass Helsingborg each year.

Fortunately for Andreas and his colleague, Monica Bengtsson, who works for the City of Helsingborg to convince cruise ships to visit her fine city, some of those ships do stop. If you’re on board one of those this summer, you can brag that you know the name of the castle across the strait.

Coming in my next post: a few recommendations for those visiting Helsingborg. And then we move on to Sweden’s beautiful capital, Stockholm, the self-proclaimed Capital of Scandinavia.

By now, you know the name of band in the photo, right? If not, watch the video. Now maybe you can tell me this, what are their names? A hint: Their names form the acronym of the band’s name.
