1. Preheat the oven to 250°F (130°C). Beat the egg whites in a bowl with an electric mixer until soft peaks form. Beat in the brown sugar, 2 tbsp at a time.

2. Line 2 baking sheets with wax paper. Using a heaping teaspoon for each, spoon the meringues, spaced about 1in (2.5cm) apart, on the baking sheet. Bake for 1 hour, or until they are crisp on the outside and slightly chewy inside.
