7 sugars compared
1. White granulated sugar is one of the world's purest foods. It's 99.9 per cent sucrose, refined from the natural sugars that occur in the sugar cane but with all 'impurities' such as mineral ash and polyphenols completely removed.
2. Caster sugar has the same composition as granulated sugar, but the crystals are smaller so it dissolves quickly. It's best for baking, especially light sponges and meringues.
3. Icing sugar is white sugar ground to a fine powder so it dissolves quickly and makes smooth icing.
