You will need water, sugar, unsweetened coconut flakes, a spoon, spatula and a small pot. The amount of sugar and water you need depends on the amount of coconut flakes you are sweetening. The ratio of water to sugar is one tablespoon of water to one teaspoon of sugar. This would be sufficient for a quarter full cup of sweetened flakes. One full cup of unsweetened flakes would require four tablespoons of water and four teaspoons of sugar.
Place the sugar and the water into the pot. Switch on the heat and bring the water to a boil, stirring the sugar until it is fully dissolved. Add the coconut until the flakes have completely absorbed the water. Switch off the heat in good time so you don't burn the flakes.
Once all the water is absorbed, spread the flakes with the spatula onto an adequately sized piece of wax paper or cookie sheet. Let it dry for around 30 minutes.
