Preheat the oven at 400 degrees
Follow the slicing instructions above
Combine all ingredients into a bowl. You'll need to use the mixture twice: Majority of it before baking and also for broiling.
Add layers of sliced plantains at the bottom of the dish to give it a little height if the dish is too deep and the rings of plantains will be too low.
Dip your silicon brush into your mixture and brush generously. Brush in between the slices.
Add plantain slices batches above the layer or layers of plantain
Place the batches in a circular pattern around the parameter of your dish.
Continue to fill the center with the slices. Be creative with your pattern. I left an area with just some layers of plantain slices, so that I could add a bowl of codfish for presentation purposes.
When the baking dish is completely full, use the silicon brush, and apply the mixture generously, getting into the to every slice and in between slices.
Cover with foil and bake for 35 minutes.
Uncover dish, use the remainder of the butter mixture and brush again. Broil for another 10 minutes or until top is golden brown.
Add it as a side to any menu, or allow it to be the star of your dish.
Saute the rosemary lightly and add as garnish. You can also add your garnish fresh.
