Creamy Walnut and Leek Soup

The book that provided inspiration for this recipe is very old. It was, in fact, the first cookbook written in the Slovak language. The author Ján Babilon published it in 1870 in Pest (today’s Budapest), where he owned a restaurant and worked as a chef.

There are 90 different soup recipes in Babilon’s cookbook, and while many of them are still in use today, others sound quite outlandish. Would you like the Wine Soup for the Sick or the Political Soup? How about the Crayfish Soup, the strawberry or the chocolate one?

I finally chose to try the Hazelnut Soup, albeit I made a few changes to the original recipe: we had a bag of walnuts left after Christmas from a friend’s garden, so I used them in place of hazelnuts; an addition of leek gave the soup more flavour and nutritional value.

I had to transform ancient weight units Babilon used in his book into the modern measurements and write more accurate instructions. Here is what I ended up with after a couple of experiments.ingredients for walnut and leek soup

  3. Pour in the water or the vegetable stock. Increase the heat and slowly bring to the boil. Throw in the diced breadroll, stir well and adjust the heat to let simmer for another 5 minutes.
  4. Pour in the cream and gently bring to the boil again, stirring all the time. Season with a pinch of salt and put aside. Divide into bowls and serve immediately.creamy walnut and leek soup 2For someone who had primarily used walnuts for baking cakes, this soup was a really enjoyable discovery. Filling enough to stand on its own, or followed by a light main course, the Creamy Walnut and leek Soup will surely stay in my cooking repertoire.

  1. Id love to try this one out. But ive got to ask you, what kind of cream i can buy in Kaufland/Tesco? Its a puzzle for my husband when I asked him to get me “heavy cream” at the supermarket. 😓


    1. Hi An Chi,
      in Tesco, Kaufland or other supermarkets you’ll find it under the name ‘Smotana na varenie’. It has either 10% or 12% fat content. Heavy cream is a US product and it has much higher fat content than ‘Smotana na varenie’. Light cream would be a better substitute when cooking this soup in the States.
      But if you want to make your soup creamier, go for ‘Smotana na slahanie’, which is a Slovak whipping cream with a fat content above 30%.
      Hope this will help 🙂

      1. Yes it helps! Thanks!! Last week I bought 1 Smotana na slahanie 33% to bake a cake and had no idea it was actually heavy cream. I was searching for “whipping cream” as in the recipe, now I wonder if Smotana na slahanie is whipping cream 🤔.

      2. Ive got a Smotana na varenie today. Please keep writing more Slovak recipe! I still cook the vegetable root soup you uploaded, my husband, as not a watery soup person, likes it. I love the taste of grated celery root a lot, so fragrant and sweet.
