Paper bag + banana method
Drop the avocado into a paper bag with a banana or apple, fold the top, and leave it on the counter.
Bananas release ethylene gas, which triggers ripening. The paper bag traps the gas around the avocado. 24 hours is typical.
The flour or rice trick
Bury an unripe avocado in a bowl of flour or rice. The grain holds heat and humidity, speeding ripening to 1–2 days.
Slower than the banana trick, but works if you don't have other fruit.
Don't believe the oven trick
You'll see TikToks suggesting wrapping an avocado in foil and baking at 200°F. The result is warm, soft fruit — not ripened. The flesh hasn't actually developed sugars or texture.
Use it for avocado on toast in a pinch, but don't try to make guacamole with it.

How can I tell when an avocado is ripe?+
Squeeze gently with your whole hand, not just one finger. Slight give = ripe. Hard = needs more time. Mushy = past it.
Can I store ripe avocados?+
Yes — fridge slows ripening for 2–3 days. For halves, sprinkle lemon juice on the cut side and wrap tightly.
Why is my avocado brown inside?+
Either bruised in transit or over-ripe. Color outside doesn't always match inside — it's a gamble.
