Help me to find a sauce i had in germany

When I was on holiday in Freiburg, I got a Chinese takeaway noodles and duck. They asked something in German and my friend just said yes (he lives there and speak german) . It came with this red, spicy sauce that was absolutely full of flavour. Now I’m back in Ireland and trying to order something similar, but I’ve no idea what that sauce was called. My friend just says spicy sauce which isn’t very helpful.

Does anyone have a clue what it might be? The flavours are still dancing on my tongue. Thanks
