Your avocado didn't mature in time? Too hard, you won't get anything out of it. Unless you use the secrets of the apple, salt and newspaper to be sure to quickly eat that avocado that makes you want so much.
I hate buying ripe avocados at the market or supermarket. One because it forces me to fiddle with them all first and two because most of them are black from having been so manhandled by so many unconscious fingers.
So I take them as beautiful as possible and if they're too hard, I adopt a little ritual once I get home to make them ripen more quickly.
1. I cut a small piece of skin off the larger rounded end to reveal the flesh of the avocado. I stick 3.4 grains of coarse salt in this place even if it means pressing with the back of a spoon.
2. I line a bowl with newspaper, place an apple (or banana) and my avocado in it. I finally cover with newspaper.
3. I keep my salad bowl in a dry place and as warm as possible.
Newspaper, apples and bananas speed up the ripening of other fruits and vegetables placed alongside them. It is sometimes practical, but pay close attention to your products that you would prefer to keep as they are for longer. Then move them away from the fruit bowl.
Did you already know this strange property of apples and bananas? Come and discuss it in the comments.
An avocado costs easy 80cts when it's not double. Personally, I avoid it ending up in the trash because it looks edible. To each problem its solution and for the avocado that is too young and not ripe enough, it's the same. Why lose €1 stupidly?
