I would like to add that if you're cooking yellow or ripe bananas, then there is no need to re-fry them a second time like you do with green bananas. This depends on how well riped the yellow banana is. Also, if you don't have a "tostonera" (I miss having one myself) then you can use two cutting boards. This works the same way. Finally, some people sprinkle lime juice on fried green bananas when they are done. My faminly never did, so it's a personal preference. Enjoy!!
