Green bananas all consider them useless until the moment they get yellow, which does not happen immediately.
However, there is one trick that you can use with a microwave.
First, take a spoon and hit the banana from all sides to ease the heat intake.
Then put the banana in the microwave, (about 30-60 seconds), and that’s it!
Once removed, the banana will probably look terrible, but its texture will be the same as the texture of perfectly mature bananas.
Once the banana is “over”, cool it down. This way you can get a perfectly mature and delicious banana every time.
