sugar substitue

[joannie10]

Hi there - I am trying out a dessert recipe to take to a friends tomorrow and it requires 150g caster sugar. Is there something I could use instead of caster sugar that would not spoil the taste or would it be ok to even just put in maybe 100 or 125g of sugar without it being affected too much? thanks

it depends what the recipe is. Sometimes the sugar is just for flavour, other times it is essential to the chemistry of the cooking and cutting or leaving it out will make the dish fail. What are you cooking?
Why do you want to reduce the sugar?

sorry I have been offline for a little while. It was a chocolate semifreddo - i have made it already and it was lovely but just seemed alot of sugar. I followed the recipe this time and it was quite sweet that perhaps I could just try reducing it a bit rather than using a substitute.
