Thanks SQ - I guess my post was just to inform whoever was interested on the background of halal - I'm sure being Singaporean you are well informed. My point on certification was also just a general one - I am sure the Singapore authorities do a better job of certification than elsewhere (because a lot of countries don't have a legal definition of what halal is and therefore it becomes hard to enforce a universal standard).
My question on the taste of halal vs non halal versions was tongue in cheek but if you do ever try the halal versions that you posted about - do let me know how it compares.
