ha ha ha I remember the first time I came across this: I was helping a snobby parvenu friend (friend's mother actually) with a drinks party she had arranged to show off her new big Georgian pile, and she had invited another snobby friend (but a bit less parvenu) also to help. In an attempt to bond with this tailored, lipsticked, coiffed (probably set under one of those hot domes with "setting lotion") conical-bra'ed, sort of county type, you know, with long, long feet in huge shiny boaty court shoes (I was about 25 and wearing a hippy skirt with ballet flats from Shoe Zone), I asked her for her recipe for her Special Crisp Biscuits.
OMG. The horror. You could have heard a pin drop. The cat looked at me, shook her head in a "this won't end well" way and stalked away from the aga.
She got over herself eventually, clearly making a huge effort For The Sake Of Mrs B (they had known each other for 30 years and called each other Mrs hiis and Mrs That), did a big wrenching sort of swallowing motion, blinked and said "well as I suppose we will never move in the same circles, I suppose I could share it with you."
The special crisp biscuits - which are vile - are made of crushed crisps and grated cheddar cooked to a sort of condensed, flat, here-comes-your-coronary pill.
I will never make the disgusting things of course. I hope someone on here does and offers them to her at a drinks party.
