For me, cheese has always been 'poison'. Having an allergy? intolerance? not to lactose but to the bacteria that 'turns' milk into cheese, yogurt, sour cream, etc. the slightest bit (like the grated cheese I discovered stuck to the bottom of the BLT I ate last week - presumably picked up from the preparation area) leaves me with 2/3 days of rumbling tummy, gas and worse. I so wish that restaurants would stop adding these cheesy things to sauces, soups, deserts and salads willy nilly and unannounced.
I don't just hate cheese - I actually FEAR it.
