Firstly, with around 100 guests of which around half are children, how many people should i aim to make hot chocolate for? I am doing mulled wine too (just for the adults!). i am assuming some adults will prefer hot chocolate to mulled wine and so i am not sure whether to do hot chocolate for say 70? or more? and then, how do i make it? i have an AGA and some big pans but do i make a paste with an entire tub of hot chocolate and milk and then gradually add milk, warming and stirring? or should i do it differently?
