Using plantains to replace French fries is a brilliant idea. The consistency of green plantains is very similar to that of a potato, and when you fry them in hot oil, they brown very easily and the taste is very similar. A few days ago, I made them for my kids and they didn't even notice that I used plantains. Serve them just as you would French fries, with ketchup, salsa or salt. This time I wanted a bit of heat so I sprinkled them with chili powder, paprika and salt. Delicious!
