Silky leek and potato soup made in the Lattveo One plant milk maker

Leek & Potato Soup (in a Plant Milk Maker)

This is the recipe that proves your milk maker was never just a milk maker. No cream, no roux, no saucepan — and a velouté so smooth people assume you spent an hour on it.

You'll need

  • 2 leeks, washed thoroughly and sliced
  • 300 g potatoes, peeled and cubed
  • 700 ml water or vegetable stock
  • 1 tbsp olive oil
  • Salt and white pepper
  • Optional: a spoonful of your own cashew milk, to finish

Method

  1. Wash the leeks properly. Slice them lengthways first and rinse between the layers — grit in a velouté is unforgivable.
  2. Load the jug. Leeks, potatoes, stock and olive oil. Do not fill past the max line.
  3. Press Smooth soup. The machine heats, cooks and blends in one cycle. Walk away.
  4. Season at the end. Salt and white pepper. Taste. Season again — potatoes drink salt.
  5. Finish. Swirl in a spoonful of homemade cashew milk and a thread of olive oil.
Why this works in a milk maker. Most plant milk machines only blend cold. Lattveo One has an 800 W heating element, so it genuinely cooks the potatoes rather than pulverising them raw. That is the difference between soup and cold vegetable smoothie.

Make it your own

  • Richer: add 20 g cashews to the jug at the start. They blend invisibly and do the job of cream.
  • Lighter: swap half the potato for cauliflower.
  • Cold version: chill it and you have vichyssoise. Same jug, same recipe, different season.

Freezes beautifully for up to 3 months. Make double.
