avocado
A creamy, high-fat fruit with a large central pit; eaten raw, mashed (guacamole), or sliced once ripe and soft.
Buying guidance
Buy according to when you'll use it -- firm, hard fruit needs a few days at room temperature to ripen, while one that yields gently to palm pressure (without feeling mushy) is ready now. Skip any with deep sunken spots or visible mold. Skin color is a useful ripeness cue for Hass avocados specifically, but not for every variety.
Substitutions
- Mashed white beans, hummus, or Greek yogurt -- reasonable for creamy texture in a dip or spread, though none has avocado's buttery flavor.
- For slices, there's no close substitute -- pick a replacement for the role it plays (creaminess, mild flavor, visual green) rather than trying to match the taste.
Tips & common mistakes
There's no real shortcut to ripening an avocado faster than a day or two at room temperature -- a paper bag with a banana speeds it along a bit by trapping ripening gases, but a microwave just softens it without developing real flavor, leaving mushy, grassy-tasting fruit. When removing the pit, strike it with the knife's heel at a shallow angle rather than a hard downward chop, since it's harder and more slippery than it looks.
Storage
Cut flesh browns within minutes of hitting the air; a squeeze of lemon or lime juice slows this considerably, and pressing plastic wrap directly against the cut surface -- not just covering the container -- keeps out the air that causes it. Leaving the pit in the unused half doesn't meaningfully slow browning on its own; it's the covering that matters.
