Preheat the oven to 325 degrees F

Wrap each cone in a piece of foil and make sure they fit on the rack standing up between 2 "bars" of the grates.

In a bowl, mix the coconut, condensed milk, and vanilla.

Whip the egg whites and salt on high speed in an electric mixer with the whisk attachment until medium-firm peaks. Fold the egg whites into the coconut mixture.

Scoop batter into the cones, not filling too high.

Stand the cones up in the oven and bake 25-30 minutes until golden and cooked through.

When cool, drizzle with melted chocolate.
