Tostones, or Fried plantains is a side dish in Latin Amercan countries. Like french fries are served here. It is basically a unripe plantain fried twice. I use the ripe plantains too. They come out tasting sweet, almost like a funnel cake.
1/2 to 1 Green plantain per person
Heat oil. Slice into 1/2 to 3/4 inch thick pieces. Place in the hot oil and let them lightly brown on both sides. About 5 to 6 minutes. Take them out dry some of the oil off. Let cool and then smash them. Put them back in the oil and let fry for another minute of two till they brown again. Let cool a little. If you are using the green plantains the traditional topping is salt or a garlic sauce. Some people even put cheese on them. So if you find a vegan cheese to make a cheese sauce out of you could try that.
I have never tried them with cheese.
When I use a yellow plantains I eat them without a topping, kinda as a dessert. But you could serve with powder sugar, vegan vanilla icecream, homemade vegan caramel. But I still enjoy them plain. :)
