Coconut-Macaroon Nests

Preheat oven to 300 degrees. Coat mini muffin tins with cooking spray.

In a bowl, stir together whites and salt with a fork; mix in coconut. Drop 2 tablespoons of mixture into each prepared tin.

Lightly press mixture into bottom and up sides of each cup. Bake until light golden on top, 28 to 30 minutes.

Let cool in tins on a wire rack 10 minutes, then run a thin metal spatula around sides to loosen. Lift out of cups; let cool completely.
