Simple and easy cauliflower soup with just cauliflower, butter, salt, olive oil, and chives.
To take this soup from simple to sublime, add a dash or two of truffle salt or truffle oil to the soup when serving.
- Florets from one head of cauliflower (tough core of cauliflower discarded)
- 1 quart of water
- Unsalted butter
- Olive oil
1 Bring 1 quart of water to a rolling boil in a medium-sized pot. Add 2 teaspoons of salt to the water (if using salted butter in this recipe, use only 1 teaspoon of butter). Add the cauliflower florets, and cook until cooked through, about 4 minutes. Use a slotted spoon to remove florets to a bowl. Reserve cooking water.
2 Working in batches, fill a blender half-way with cooked cauliflower, add enough cooking water to the blender bowl so that it comes up a quarter of the way. Purée until smooth. You want the consistency to be that of soup, so if you need to add more water, do so. For each blender batch, add salt and butter to taste (about 1/2 teaspoon of salt, and about a tablespoon or more of butter for each blender batch). Since you are using only lightly salted cooking water for a base, not stock, you will need to salt this more than you would otherwise.
3 Serve immediately into bowls. Drizzle olive oil over the top and sprinkle with chopped chives.
