If they’re all the same firmness sort them thusly:
- In a closed paper bag with a banana or apple (ripen fastest)
- In a closed paper bag by itself (ripen quickly but not as quickly as with a banana/apple)
- On the counter (you could consider this your control avocado)
- In the refrigerator (ripen the slowest - if at all!)
Avocadoes (nearly all fruits, TBH) ripen faster in the presence of ethylene gas, which bananas and apples emit fairly prodigiously. The riper the banana/apple, the more ethylene they produce, and rotten bananas or apples are veritable ethylene gas bombs. That’s why one bad apple can make an entire bag of apples go bad seemingly overnight.
