About this dish
Blending half the soup and leaving the rest chunky creates a rich, creamy body without any cream — the secret is sweating the leeks low and slow in olive oil until completely silky before a single drop of stock is added.

Method
Halve the leeks lengthways, rinse thoroughly under cold water to remove all grit, then slice into half-moons. Finely dice the onion, thinly slice the garlic, peel and cut the potatoes into 2 cm cubes, and set each aside separately.
Warm 3 tbsp olive oil in a large heavy-bottomed pot over a low heat. Add the leeks and onion with a generous pinch of salt and sweat, stirring occasionally, for 18–20 minutes until completely soft, collapsed, and just beginning to turn golden at the edges — do not rush this step.
Add the garlic and cook, stirring constantly, for 2 minutes until fragrant but not coloured.
Add the potatoes, white pepper, and nutmeg, stirring to coat everything in the oil for 1 minute.
Pour in the hot vegetable stock, increase the heat to medium-high, and bring to a boil — this should take about 5 minutes.
Reduce the heat to a steady simmer and cook for 15 minutes until the potatoes are completely tender and collapsing at the edges when pressed with a spoon.
Ladle roughly half the soup into a blender, blend on high until completely smooth, then pour the blended portion back into the pot and stir to combine.
Taste and adjust seasoning, ladle into bowls, finish each with a drizzle of olive oil and a scattering of fresh chives.
