I love this stuff!!! I believe it’s used in a similar way to Worcestershire sauce but without the anchovies. I have it in stews, casseroles, on baked beans, potato, vegan cheese on toast, etc. etc. I guess it has a vinegary brown-sauce taste but with less sharpness and more depth!
It’s available all over Yorkshire- they sell it in all the museums in Sheffield and in supermarkets and delis. Unfortunately it’s harder to find in London so I get my supplies up north.
Brilliant vegan sauce!
