I still use all those things, not haslet. It's not something I have ever tasted. I make stuffed hearts, liver and bacon, I make liver stroganoff rather than steak, kidney and bacon pilaff, chicken liver pate, I boil up pigs trotters, then roast them. My mother makes brawn, delicious as long as it has enough herbs and seasoning, I buy jellied eels in the local market, and make rollmops, which I suppose are semi-pickled herrings. I remember my mother making two dozen one night, for the next night, but my father came home from a night out and fancied a snack - he ate a dozen of them and she didn't talk to him for a week! I have always loved them, but prefer the gentler home-made ones.
I hate junket and blancmange and tapioca, but I make our rice pudding in the winter. We like cods roe, and sprats - and fried whitebait. I haven't had tripe for a while, but I do make a very nice blanquette of veal substitute with it, I could never bear tripe and onions again after having made it that way. We have oxtail stew every winter. The kids have always loved it. I can buy a whole tail from my butcher for £4.
