To my knowledge the difference between Kosher and hilal are hilal is only a way of preperatoion of the animal for slaughter and the slaughtering process. Kosher is a whole preperation of the way things are cooked, each different type of food is broken down into sections such as, meat, fish dairy, poultry, fruit& veg and are all prepared in separate kitchens so they dont contaminate one and other and each seprate preparation area has been blessed by a Rabbi, this is just a basic break down of what kosher is there is a lot more to it than what I've said but it gives you an idea of how it goes.
