I picked up a bottle of Suree Sriracha chilli sauce in B&M today (?1.50 ish) because people have been mentioning it and I've been meaning to try it for years but just never got around to it. Well, what a disappointment! It's just a less garlicky version of Maggi garlic-chilli sauce.
The up-side is that I looooove Maggi GC sauce so the disappointment was that I should have saved my pennies and just bought the superior brand.
Using this in a curry though? Not done it and not sure I would like to. For me I think it'd be like using Mr Naga in a curry and as much as I adore that pickle I can't abide it in a curry.
