I've also heard the version of Padma and while I have huge respec t for her, I have to agree with Pippa, that the origins may be somewhat different.
I have to say, though, it is rare to get decent fish and chips anywhere now.
I came to this country in the mid 60s and lived in a small village in the Midlands. There was a chip shop there of the type that were all over the UK. My first experience of English food.
The point was, they used dripping to fry.
You can buy dripping in some butchers and supermarkets. though only small quantities. If you get some, try shallow frying with it. Not quite the same as the old chippie deep fried but the taste is still quite amazing.
Frankly, it's my experience that French food is all colour and no taste. It's also incredibly greesy for some strange reason. Though not being a chef, I have to assume it's because it's French.
English food may be quite plain but, health fascists aside, the taste is incredable. Buy meat now-a-days, the fat has been cut off. Supposedly it cloggs our arteries. Yet people ate it for centuries, often all they did eat.
