Well yeah any meat based animal food would obviously be repulsive but no human likes the smell of pedigree chum surely?!
I hate the smell of plain lamb with too much fat on it cooking. Like it smells like old rancid dishcloths. Just a really dirty smell. I only like lamb when it's been cooked with lots of spices and flavourings.
I used to live near a biscuit factory and that was amazing.
Semolina and custard from school dinners was appalling smelling, and worse tasting. In fact all the smells of 80s school dinners!
