Hello everyone,

I am new to this site, I discovered while looking for good curry recipes as I am cooking for over 100 guests at my husbands 40th birthday party next weekend!!  (100 serving and ex soldiers. I must be mad!!!)  Anyway I have today cooked a chicken korma and a madras from recipes found on this site.  They have both turned out fantastic, even if I do say so myself.  But can anyone tell me how I go about making up larger batches, ie. if I am following a recipe for 2 and I want to make 100 portions do I just multiply by 50?
