About tostones with platano Hawaiano, the Hua Moa. The flesh is less dense than regular plantains. You need to cut the slices thicker to 3/4 to 1 inch thick. After the first fry on medium heat just press down slowly with the maseta. Don't try pounding - they will bust up easily. Second fry on med-high till golden brown.
And what happened to dipping in good old mojo - garlic, olive oil, lemon? Using ketchoop - yuck!
