Now hear this: “wooster sawss”.
Woos like woof. Sawss like the sor in sorceror.
I have learnt that any other ridiculous pronunciation that heeds the spelling of the word is to be derided and spat at.
Now let’s move on to “Beaulieu”.
Edit: bollocks, sor in American has a loud rolling r. Don’t do that. Saw. Sawss.
I don’t know that I would put it anywhere near steak but it is a must with bacon.

Lea & Perrins is great.

I have a theory that anyone feigning enthusiasm when tucking in to roast eyeballs/sheep’s brains/tongue is doing it primarily to yank the chain of passing gringo/Anglo tourists. Bet you won’t eat this! subtext/you lily-livered too-rich imperialist sissy /subtext
Also: It’s wooster sauce, FFS. How hard is that?
Wercherchercher sauce is regularly used in hispanic cuisine as a way to give food some extra umami 
i’d say between it and soy sauce i’d prefer Worcester
Well, there’s this…
