A few months ago, the world was >melting in sorrow after it was revealed that M&M's aren't always halal-friendly. Well, Oreos have become the center of debate, now.
In recent days, several Twitter users have been questioning the cookie brand over its halal status. On its website's FAQ section, Oreo explicitly states that their cookies are not halal certified.
However, the basic ingredients are in fact halal by nature - just like water. These include sugar, flour, oil, cocoa, chocolate, corn syrup, and several other halal-friendly components.
