Method
Slice the leeks, dice the onion, slice the garlic, and cube the potatoes, keeping the potatoes submerged in cold water until ready to use.
Melt the butter in a large, heavy-bottomed saucepan over medium-low heat. Add the leeks and onion, season with the fine sea salt, and cook, stirring occasionally, until completely softened but not coloured — about 15 minutes.
Add the garlic and cook, stirring, until fragrant — about 2 minutes.
Drain the potatoes and add them to the pan along with the vegetable stock. Increase the heat to medium-high and bring to a gentle boil, then reduce heat to maintain a steady simmer.
Simmer uncovered until the potatoes are completely tender and beginning to break apart when pressed against the side of the pan — about 20 minutes.
Remove the pan from the heat. Stir in the whole milk and double cream.
Working in two batches, blend the soup in a high-speed blender on full power for 2 full minutes per batch until completely smooth.
Pass the blended soup through a fine-mesh sieve into a large bowl, pressing with the back of a ladle to extract every drop.
Whisk in the cold crème fraîche until fully incorporated. Taste and adjust seasoning with white pepper and additional salt.
Cover the surface directly with cling film and refrigerate until thoroughly chilled — at least 4 hours, or overnight.
Ladle into chilled bowls. Finish with a scattering of snipped chives and a pinch of flaky sea salt.
