Avocados are the most capricious fruits around. In addition to being pricey, of course. I find it hard to judge when they are really ripe. I press on this side, it feels ripe. I prick the other side, it does not feel ripe! And sometimes, they turn bad so quickly!
I usually leave them to ripen in the following two ways.
1. Wrap in newspaper and to place in a drawer. I tried this a few days ago. It works well. I left two medium sized avocados in the drawer this way. When I took them out, they were just rightly ripe. The skin was greenish-brown. The skin peels off easily. The flesh was greenish yellow. And yes, heavenly smell! After that, I kept them in the fridge to try and keep the freshness.
2. Place in a sack of raw rice. This trick works really well. All too well for me. If you let it pass by just one day, you will find your avocados in a sad sluggish state.
Anyway, I think the main thing is not to forget about them. Which ever method is used, if you do not check the avocados every now and then, you will miss the right time to eat them. They are such delicious fruits, and the effort is so much worth it.
And the best way to eat them is the simplest way: Lightly sprinkle some sugar on them. *Yum*
