I just stumbled upon an extensive website devoted to British food that
includes many many recipes:

http://www.greatbritishkitchen.co.uk/cookbook.htm

Now I hope nobody will sneer, because this crowd at RFC should know by
now how rich and diverse British cuisine is. I found the site while
looking for a recipe for Marlborough pudding, an 18th century Brit and
American pastry that's new to me. It's a sort of chess pie with stewed
apples.

A few of the soups, for instance: Asparagus, cock-a-leekie, cold
spiced beef and hot soup, Cornish crab, carrot and ginger, Highland
game, green pea and cucumber, etc. etc. And that's just the soups.

I haven't even begun to explore all the recipes, and the other aspects
of the site, but I expect I'll be spending quite some time there.

Hope you find it of interest.
