Chilled Avocado Lime Soup

Avocado is one of the few fruits that ripens after it's picked, which is part of why a good soup like this depends on timing. Buy the avocados a few days ahead and let them sit on the counter until they give slightly when you press the skin near the stem. A ripe Haas avocado has a dark, bumpy peel and a buttery center, and that creaminess is what carries the whole bowl. If the flesh is stringy or bitter at the edges, the soup will taste flat no matter how much lime you add.

The base is built the way many old-fashioned chilled soups are. You soften a little onion and garlic first, so their sharpness mellows before it gets blended into something smooth. The lime juice does more than add tang. Acid keeps cut avocado from browning quickly, so the pale green color holds up in the fridge better than you might expect. A splash of dry sherry adds a nutty depth that makes the soup taste like it was planned, not thrown together.

Cold food needs more seasoning than warm food, so taste after chilling, not before. Cold dulls salt and acid, which means a soup that seemed perfect at the blender can come out tasting a little lifeless in the bowl. Add a pinch of salt or another squeeze of lime at that point. Also keep in mind that a chilled soup thickens as it sits, so if it feels heavy when you pull it from the fridge, stir in a spoonful of milk or cold stock to loosen it.

Leftovers keep for a day or two in a sealed container. Press plastic wrap directly onto the surface to limit air contact, and expect a little darkening on top. Stir well before serving. It does not freeze well, since the texture turns grainy once thawed, so it's better to make only what you'll eat in the next couple of days.

For serving, this soup sits nicely beside something warm and savory. A plate of Baked Eggs with Parmesan and Cumin makes a light lunch that goes well with the cool, citrusy bowl. For a fuller meal, pair it with Sheet Pan Orange Salmon with Broccolini so the richness of the fish balances the smoothness of the soup.
