Something weird happened a few months with Green and Pleasant, when the reddit algorithm decided G&P is a general interest UK sub and not a lefty space, so now every thread consists of about 20% lost right wingers who don't even realise they are brigading a lefty space and are genuinely confused when they get piled on for their stupid positions.
Its quite strange - not something I've seen happen with any other subreddit.
liquor in this context isn't booze, its 'liquor sauce' which is a sort of herby, parsley bechamel (its usually quite thin and light for a bechamel)
Its quite nice - if you're going for a specialty london food I would definitely go for pie mash and liquor over fucking jellied eels
