Trust me preparing hilal is much simplier thaan preparing kosher, I've done a few functions in Sydney that involved kosher and for lack of a better word it's a pain in the A*&, as a lot of the time the rabbi's stay to make sure you adhere to the rules you have to take every single knife that you have in your arsenal as you cannot cut fish with the same knife you cut your vege with and you can't use your meat knife to prepare the chicken etc etc.
