Ingredients

Why metric?

Metric avoids regional spoon ambiguity. US uses 5 mL tsp, 15 mL tbsp and 240 mL cup. Small masses stay in grams unless a verified recipe conversion exists. More on measurements

  • 300 g cauliflower, cut into small florets
  • 190 g potato, peeled and diced small
  • 70 g leek, white part only, sliced thin
  • 32 g unsalted butter
  • 100 ml reduced-salt stock (100 g)
  • 60 ml water (60 g)
  • 200 ml reduced-fat milk (206 g)
  • 60 g skim milk powder
  • 30 g parmesan, finely grated
  • 4 slices soft white bread, crusts cut off (110 g trimmed)
  • black pepper, to taste

Method

  1. Melt 16 g of the butter in a saucepan over medium-low heat and soften the leek for 6 minutes without letting it colour.
  2. Add the cauliflower, the potato, the stock and the water. The liquid will not cover the vegetables and does not need to; the lid does the rest.
  3. Cover and simmer 18-20 minutes. It is ready when a floret crushes against the side of the pan under almost no pressure. Cauliflower that still squeaks under a spoon blends into something faintly grainy, so give it the extra few minutes rather than the benefit of the doubt.
  4. Blend until smooth, then whisk in the milk, the milk powder and the Parmesan off the heat so the cheese melts without stringing. Warm through gently and add pepper.
  5. Taste before reaching for salt. Between the Parmesan and the stock most people find it does not need any, and if it tastes flat it is usually thin rather than unsalted; another spoon of milk powder fixes that.
  6. Toast the trimmed bread, butter it with the rest of the butter and cut it into fingers to go alongside. The soup thickens in the fridge and comes back with a splash of milk.

Safety and storage

Keeps
