Very fine crystals make this sugar excellent for sprinkling and including in recipes. It is known as caster sugar because it is suitable for placing in a caster - a jar or bottle with a perforated top, similar to a flour dredger. Uses: For sprinkling over fresh fruit or cereals or including in creamed mixtures, meringues and baking. To store: Keep in a cool, dry place for up to 1 year and once opened store in an airtight container to prevent the sugar from going hard or damp.
