Fresh danish strawberry dessert for summer

Cold buttermilk soup equals summer for many Danes. This strawberry buttermilk soup is Danish summer in a bowl. It is a buttermilk soup made with fresh strawberries, which can be eaten as a fresh and delicious summer dessert or as a light meal for hot days.

Cold buttermilk soup is something our kids love, and they especially love when a portion of strawberry buttermilk soup is ready when they come home from school and kindergarten. This is exactly what you need after a day of speeding in the heat.

In Denmark, we can buy ready-made cold buttermilk soup. There are probably many who choose the ready-made solutions when we talk cold buttermilk soup, and that can also be quite nice.

But it’s actually really easy to make homemade cold buttermilk soup, and when you can just sneak a portion of strawberries in, it just gets extra good. You can easily make this dessert in 10 minutes, so there is no excuse for not making it.

Ingredient notes

Strawberries – Of course, strawberries must be used in the recipe. You can use fresh or frozen, thawed berries for the cold buttermilk soup itself, as topping fresh strawberries are of course preferable.

Danish tykmælk and buttermilk – I think a cold buttermilk soup made on egg yolks with danish tykmælk and buttermilk will be absolutely perfect. It is creamy and delicious while being fresh and having a natural acidity. Danish tykmælk is not a type of dairy you see in other countries though, so if you live in a place where you can not get tykmælk, then you can substitute it with plain yogurt 3.5% fat. The taste will still be great.

Lemon – You can flavor your cold buttermilk soup with lemon zest and lemon juice. It gives a nice taste. Of course, how much you need depends a lot on the strawberries you use and how sweet they are. You have to start with a little, and taste before you add more.

How to make cold strawberry buttermilk soup?

Cold buttermilk soup is one of the easiest desserts to make.

The first thing you need to do is whisk the egg yolks together with the sugar.

Then add vanilla, buttermilk, and tykmælk, and finally blend strawberries and pour the pureed strawberries into the soup. I also love to add a little lemon zest and juice but remember to taste the soup before adding too much lemon.

The buttermilk soup is served with homemade kammerjunkere and fresh strawberries.

How to serve cold strawberry buttermilk soup?

This dish is typically a dessert served in Denmark in the summer, or sometimes on hot days, we eat it for dinner.

Traditionally cold buttermilk soup is served with danish kammerjunkere, these small double-baked biscuits. You can also add fresh strawberries or other fruit or barries.

What is Danish tykmælk?

Danish tykmælk translates to “Fat milk” and is a kind of fermented milk product. In Denmark, you can buy it in most supermarkets. It can be made at home, but it takes a couple of days to ferment the dairy. For this recipe, you can substitute it with plain yogurt with 3.5% fat to get the same creamy texture. Maybe you need to add a little extra lemon to get the right acidity.
