New Potatoes and Buttermilk Soup

New potatoes with butter and dill, served with a glass of chilled buttermilk, are a beloved summer comfort food in the Polish countryside. Having spent many afternoons enjoying this satisfying combination, I got to daydreaming about a soup version, and here we are. Though it’s extremely creamy, there’s a tangy punch thanks to the black pepper and buttermilk. Fresh dill makes this soup even more authentic, so don’t skip it.
