Which Christmas dish has caster sugar in it?

There are many Christmas dishes that could use caster sugar, as it's a versatile ingredient! To give you a better answer, I need a little more information.

Can you tell me:

* What type of dish are you looking for? (e.g., dessert, savory, drink)

Once I know that, I can give you a more specific answer.
