Can brown sugar be a substitute for castor sugar?

Similarities:

* Both are granulated sugars, meaning they have a similar texture.

* They are both used in baking and cooking.

Differences:

* Moisture: Brown sugar contains molasses, which gives it a slightly moist texture and adds a caramel flavor. Castor sugar is pure sucrose, making it drier and less flavorful.

* Flavor: Brown sugar has a more complex flavor due to the molasses.

* Color: Brown sugar is darker than castor sugar.

Substitution:

* For sweetness: 1 cup of brown sugar is roughly equivalent to 1 cup of castor sugar.

* For texture: Brown sugar can be slightly sticky, so you might need to add a bit more flour to your recipe if using it as a direct substitute.

* For flavor: Be aware that brown sugar will impart a caramel flavor to your baked goods.

Important considerations:

* Type of brown sugar: Light brown sugar is milder in flavor and has less molasses than dark brown sugar. Choose the appropriate type based on your desired flavor intensity.

* Recipe requirements: Some recipes might require the specific texture or flavor of castor sugar. If you're unsure, it's always best to follow the recipe instructions.

Overall:

Brown sugar can be a suitable substitute for castor sugar in many cases, especially if you don't mind the slightly moister texture and caramel flavor. However, be mindful of the differences and adjust your recipe accordingly.
