Golden caster sugar is a type of sugar that is unrefined and processed in a way that maintains its natural molasses content, giving it a light golden color and caramel-like flavor. It is similar in texture to regular white caster sugar, but with a slightly different flavor profile. Golden caster sugar is ideal for use in creamed sponge cakes and other baked goods. It can be substituted with regular white caster sugar in most recipes, but if the recipe specifically calls for golden caster sugar, brown sugar is not recommended as a substitute due to its higher moisture content. In the US, golden caster sugar is equivalent to evaporated cane juice.
