Hi I am an Essex boy, don't worry about Sir Keith, he is a scouser, and comes from the upper provinces, you are living in the more refined part of the country, so his brand of humour may be hard to understand...
So you want ingredients, well firstly, you could get your partner to take you to Hoo Hing, there is one just off Whalebone lane south going in towards Dagenham, the address is on internet under Hoo Hing.
Secondly, if you want a day out, get on the Tube, or take the train into the city, depending on where you live in Essex, you take the One network into the city, Liverpool street station, then get on the Picadilly line, get around to Earls Court station, out of the station turn left, and walk up Earls Court road, and look for Hogarth Place on your right, there are 2 Filipino dedicated supermarkets, one is called Manila Supermarket.
They should have all your ingredients, I hope this information has helped.
