Langkah 1
Heat oven to 180°C. Grease a round cake tin, then line the base with parchment. Using electric beater, whisk the egg whites, cream of tartar and a pinch of salt until stiff but not dry. Add a tablespoon of sugar, then whisk until the mixture thickens again to make stiff peaks. Repeat with the rest of the sugar, spoon by spoon, until the mix resembles thick shiny shaving foam. Set aside.
