Soup Waltz
It became a classic and one of our favorites right after I came up with the recipe. And it will definitely make you want to dance (inspired by a traditional Viennese soup, Rcp# 69)

Ingredients for ‘Soup Waltz’
- 45-50g of grated parsnips (two medium parsnips, cleaned)
- 45-50g grated fennel (core of one medium fennel bulb)
- 5-6 tablespoons of canola oil
- 5 precooked, crumbled chestnuts
- 5 medium-sized, firm-cooking potatoes, peeled and cubed
- 1 liter of strong vegetable broth (homemade; see [AnyBroth])
- 1 teaspoon salt
- Freshly ground pepper and freshly ground nutmeg
- 150g large king oyster mushroom heads (you need about 5 – 6 of them), cut into small cubes
- 3 tablespoons chives, chopped (fresh or frozen)
- 1/2 teaspoon bear‘s garlic in oil or dried bear‘s garlic
- 200 ml hot Water
- 1 – 1 ½ tablespoon cashews, crushed and ground into flour using a mortar and pestle
- You will also need a pot that holds three liters and a stone mortar for grinding the cashews.
Cooking Instructions for ‘Soup Waltz’
- Add 3 tablespoons of canola oil to the pot and sauté the mushroom cubes until they are ready (they will start to smell like mushrooms).
- Turn the heat down to low, then add the crushed cashews. Stir until the cashew flour has picked up just a little color. Be careful, as this will burn quickly. Add 250 ml of broth plus 200 ml of hot water, and bring to a boil. Turn off the heat, then add nutmeg, salt, and bear’s garlic. Pour the mixture into a heat-resistant bowl (it’s best to place a wet cloth under it) and set it aside.
- Reuse the same pot with 2 more tablespoons of canola oil to sauté the grated fennel and parsnips. Once they are lightly browned, add the crumbled chestnuts and the remaining 750 ml of broth. Stir well.
- Bring to a boil, then add the potato cubes. Simmer on medium heat until the potatoes are done but still firm.
- Combine the soup and the mushrooms in liquid, stirring gently. Turn off the heat and remove the pot from the stove.
- Add the chives and let stand for 8-10 minutes, covered with a colander or lid with a spoon underneath.
This serves as a starter soup for four to five people or a generous lunch for two.
Side Notes:
- This recipe is the twin of the one with the Ingredient Special on King Oyster Mushrooms (‘Oyster with Plenty Pearls’ → recipe [‘Mushroom in Pyjamas’]). In that recipe, you use the stems, but here, you need the heads. As I wrote in the ingredient special, those heads are a perfect replacement for porcini mushrooms. Porcini mushrooms are not easily available in many regions and are not available year-round, unlike the king oyster mushroom. I love that mushroom; it’s so versatile.
- The “Soup Waltz” was inspired by a hearty Austrian dish and local specialty from Vienna. Although the original called for plenty of fat (lard) and other ingredients that aren’t exactly light-footed, I figured you don’t really need those to get into the mood. Ah, those wonderful Viennese waltzes and the annual opera ball…
