Koldskål quenches Danish thirsts on warm summer days with its creamy, tangy complexity. This cold soup-like drink evolved from the Danish tradition of using buttermilk and yogurt, staples of the Nordic diet for centuries. Served ice-cold, its combination of vanilla sweetness and lemon brightness makes it distinctly refreshing without being cloying.
In a large bowl, combine the buttermilk, yogurt, sugar, vanilla extract, lemon juice, and salt.
Whisk together until the sugar is fully dissolved and the mixture is well combined.
Cover the bowl and refrigerate the Koldskål for at least 1 hour or until thoroughly chilled.
Serve the Koldskål cold, garnished with fresh mint leaves or lemon zest if desired. It can be enjoyed as a refreshing dessert or a light summer soup.
Koldskål is a creamy Danish cold drink that falls between a beverage and a dessert, made from buttermilk and yogurt blended with sugar, vanilla, and lemon juice.
Koldskål originates from Denmark, where it's an iconic summer refreshment enjoyed chilled, particularly during May and June when berries are in season.
Essential ingredients are buttermilk, plain yogurt, granulated sugar, vanilla extract, fresh lemon juice, and a pinch of salt for balance.
Use full-fat yogurt and buttermilk for richness, whisk thoroughly until smooth, taste and adjust lemon and vanilla, and chill for at least one hour before serving.
Serve very cold in glasses or bowls, often with fresh strawberries or raspberries, crispy butter cookies, or sweet pastries for dunking.
