When the summer hits Denmark with our yearly heatwave, people go nuts for koldskål. Not just as a snack, but for dinner. You cannot get any ready-made koldskål in the stores. It doesn’t matter because the homemade kind is just so much better. This is my recipe for buttermilk koldskål with kammerjunkere.
It may seem odd to be eating this dish for dinner; when it’s so hot that you can barely move, you want something cold. I tell you, it’s the craze in Denmark. So why not just eat a cold refreshing soup made with buttermilk.

Koldskål is a cold soup or a drink made from buttermilk enriched with various ingredients, like, egg, sugar, cream or other dairy products, vanilla, and lemon.
The dish evolved when commercially-made buttermilk became available in Denmark at the beginning of the 1900s. Since 1979 Danes have been able to buy ready-made koldskål in the supermarkets, which made it blow up.
It’s most commonly eaten with tvebakker, a rusk, a hard unsweetened twice-baked biscuit, or kammerjunkere, a twice-baked cookie. When I was a kid, and we didn’t have much money, we’d mainly have tvebakker and then a couple of kammerjunkere, simply because tvebakker were much cheaper.
In my family, we’ve always eaten strawberries with our koldskål because the heat usually hits in the middle of strawberry season, sometimes in July.
The conclusion of this buttermilk koldskål recipe
So, what do I treasure in a classic Danish buttermilk koldskål with kammerjunkere?
Well, the soup itself should be both sweet and tangy. Not by a crazy amount, because otherwise, you’d be sacrificing the refreshing part. You should serve it as cold as possible.
The cookies must be extremely crunchy, so they can lay in the soup without becoming soggy. Nobody wants a soggy cookie. They should absolutely be smelling of butter and have a rich mouth feel.
Since you’ve read this far, you can probably imagine that that’s exactly how I designed the recipe to be. It’s so good.
