There’s been some recent confusion over what it is which makes McDonald’s fries so special. It turns out that some branches of McDonald’s are serving up fries with a little-known ingredient added to the mix: “natural beef flavouring”. The beefy addition gives the fries an extra kick of flavour, but it means that they aren’t vegan, since the flavouring is actually made from milk. However, you won’t find this extra ingredient in every branch – and you certainly won’t find it in any UK stores. That’s because Maccies uses different recipes in different countries, with the extra flavouring added in US and Canadian McDonald’s stores. In British branches, the fries are milk free, and don’t contain the beef flavouring which has surprised some American customers. More
