Step 1

Put the potatoes, onions, most of the leeks (keep a handful of the white leek for later) and chicken stock into a soup maker and press the ‘smooth soup’ function. Make sure you don’t fill the soup maker above the max fill line.

Step 2

Once the cycle has complete, add most of the cream and all the milk, and blend again briefly. Use the ‘keep warm’ or ‘heat’ function to keep the soup warm while you make the topping.

Step 3

Finely shred the remaining white part of the leek. Heat the butter in a small frying pan, and gently cook the leek for a few mins until it is softened but not coloured.

Step 4

Drizzle the remaining cream over the soup, and top with the leeks, a scattering of chives and some black pepper.
