Danish strawberry buttermilk soup – aka koldskål
Summer in Denmark means eating lots and lots of koldskål, which is a cold buttermilk soup with vanilla and lemon. There are lots of ready-made variations in the grocery stores, some are better than others so the past few years I have made my own. It’s really easy to make and I don’t have to worry about which preservatives have been added. And I can also make my own variations. Like this strawberry version which is so much better than the store bought strawberry version. You just can’t beat fresh strawberries.
I also baked a batch of biscuits called kammerjunker, which what we usually add to the soup. They are small, light and crunchy biscuits with lots of vanilla. I bake a large batch and store them in an air-tight container so I have enough for the summer.
Ingredients (for the soup)
6 pasteurized egg yolks
50 g sugar
Juice and zest of half a lemon
2 teaspoons vanilla sugar
A few grinds of a vanilla grinder

Beat the egg yolks, sugar and vanilla sugar until the mixture is stiff and sugar is dissolved.
Pour in the buttermilk and season with lemon juice and a little grated lemon zest.
Blitz strawberries in a blender and stir into the buttermilk soup.
Serve with fresh strawberries and kammerjunker biscuits or a bit of granola.
