Had takeout from a local family owned roadside burger joint that's been around for years. Just changed ownership and ordered a burger last night. Took one bite... the smell and aftertaste almost made me sick. I couldn't put my finger on it till this morning.... like a li er smell a ND taste. I cannot be in a house that is cooking liver as I can taste it as it is cooking! Wondering about the hamburger.... this is the second time this has a happened to me. What could it be from?
