Sju sorters kakor is a Swedish phrase that translates to seven kinds of cookies. It's a tradition deeply rooted in Swedish culture, particularly when it comes to coffee gatherings known as fika. The tradition goes back several generations when it was believed to be courteous and almost expected to offer at least seven types of cookies (among them drömmar, hallongrotta, brysselkex, etc.) when you had guests over for coffee.

Offering fewer might be perceived as impolite or an indication of not being well-prepared for guests. Today, while many might not strictly adhere to the rule of seven, the phrase remains a popular representation of Swedish hospitality. Over the years, the concept has expanded from cookies to cakes and pastries.

The phrase also became the title of a popular Swedish baking book first published in the 1940s. "Sju sorters kakor" was a compilation of recipes gathered from a nationwide contest, and the book has been reprinted numerous times since, becoming something of a staple in Swedish kitchens.
