I like to try any new or unusual foods when I'm travelling so I had to give this sauce a go. It's called Sosatie Sauce and is part of a range called 'Walker Bay', a South African brand. It's a tangy, sweet and sour type sauce with a spicy, curry-like kick to it. I think sosatie sauce is a traditional South African thing. To give you an idea of what's in it, you can see a recipe for a homemade version of it here.
It goes great with grilled sausages or any barbecued food and it doesn't have that cloying texture or fake smokiness you get with a lot of barbecue and meat sauces. If it was a little thicker it would be perfect for hot dogs too. It's very nice stuff. Try it if you get a chance!
