For making weetbix I have boil water and heat some milk in the Microwave. Pour the boiling water over the weetbix then add the warm milk. Add brown sugar and a dash of cream.
Most of the time I'm to lazy to do all that but it's the way my mum made them so I sometimes do it if I feel like a treat. I think the hot water is just a way to save on milk but it melts the weetbix which Ive grown to like.
