McDonald's customers are up in arms after noticing a slight change to a popular sauce. Regulars at the Golden Arches have their go-to orders down to a tee, including their preferred choice of dip. From classic ketchup and barbecue to the bolder sweet curry or chilli options, something usually satisfies everyone.

However, the fast-food giant's Sweet and Sour sauce, a menu mainstay since 1983, has undergone a tweak that hasn't gone unnoticed. TikTok users have been vocal about the alteration, with one user, Demi (@demmmx92), slamming the revamped sauce pot as "disgusting" due to an unexpected ingredient switch-up. The comments section quickly filled up with similar disappointment.

One person commented: "I thought it tasted like apricot, it's overwhelming!" Another added: "I knew it tasted different! I thought it was just me!" A third wrote: "Honestly I'm gutted! It's the only sauce I liked from there. I can't have maccies without this sauce!" Another fumed: "How dare they change it without asking us! Not even joking I love this stuff." Another went as far as to call it "absolutely vile" now, reports the Mirror .

The sauce saga has even sparked concern among fans of other McDonald's dips. One worried fan posted: "If they've changed sweet curry I will not be responsible for my actions!" While another speculated: "I'm convinced they changed the barbecue as well now! " A third asked: "I had sweet curry the other day and swore blind it was different, have they changed them all?" Ano.
