Use only the white and pale-green of the leeks and sweat them in butter without letting them color. Any browning turns the soup gray-beige; kept pale, it blends to the ivory it should be. Serve it genuinely cold, and season a little harder since chilling mutes the salt.

Can you make Vichyssoise in an air fryer? — Yes, with an insert
Not on its own — an air fryer can’t hold a pool of liquid. You can simmer it in an oven-safe dish or a silicone insert made to fit the basket, but the broth won’t reduce or brown the way it does on the stove, and that insert comes out scorching, so use oven mitts. For real depth, a pot on the stove wins.
