Thought this was useful. I've been paying extra for fine sugar at the shops for years

That is very useful to know, I won't be buying caster sugar again.
Wow! I didn't actually realise the difference in price between granulated and caster - Tesco has the latter coming in at just under 3 times the price of the former.
That is very sneaky of them! Looking at that video though I would have to invest in a hairdryer, I wonder how many bags of sugar I would have to buy to balance that out. :o
