Preheat the oven to 350°F (180°C).
Whisk the egg whites together with the cream of tartar and salt. Continue to whisk whilst gradually adding in the sugar. Beat until the egg whites hold stiff peaks, then whisk in the vanilla and almond extracts.
6 egg whites, 1 tsp cream of tartar, 1/4 tsp salt, 3/4 cup (150 g) granulated sugar, 1/2 tsp vanilla extract, 1/2 tsp almond extract
Sift the flour into the bowl. Also add the coconut to the bowl. Fold it all together with a rubber spatula until just mixed.
1/2 cup (60 g) all purpose flour, 1/2 cup (40g) desiccated / shredded coconut
Pour the batter into an angel food cake/bundt cake / tube pan (if you use a bundt pan, I'd say you should grease it or make sure it's non-stick). and bake for 20-30 minutes. Leave to cool upside-down, on a wire rack. Once cool, loosen the edges with a palette knife and turn out onto a serving plate.
