Ripen Your Avocados
Avocados tend to have a really short window of time when they have just the right ripeness. You want them soft, but not too soft. But a watched avocado never ripens (or something like that). If you have an avocado that you’re waiting to ripen, try some flour.

First, place the avocados inside a paper bag and cover them with flour. Put the bag in a room-temperature area for about 24 hours. After a day, they should be ripe. How? Well, the flour blocks any outside moisture from turning them brown.
