Avocados are sold hard and unripe, so you need to wait a few days before they are soft and ready to use. If you need a ripe avocado before they are ready, you can use your microwave to simulate the ripening process so they will be ready for immediate use. The California Avocado Commission does not recommend microwave-ripening of avocados, so try to purchase yours two to five days before you will need them. The flavor of the avocado will be affected by microwaving instead of natural ripening.
Poke holes all over the avocado with a fork.
Place the avocado on a paper towel.
Put the avocado and paper towel in the microwave.
Set the microwave to medium heat.
Cook the avocado in the microwave for 30 seconds.
Remove the avocado from microwave and let it cool until it is comfortable to touch.
Squeeze the avocado in your hand to check for softness. The avocado should still feel firm, but you should be able to press into it when gently squeezed.
Place avocado back in microwave and cook for another 30 seconds until soft if necessary.
