Lamb. It smells awful. I don't hate to eat it because I just don't eat it.
I don't eat pork, or raw seafood (sushi) either, don't like the texture / smells.
I don't like anything that has a lot of air in it, like puffed wheat, puffed rice, rice crackers, wafers etc. I used to hate pop corn, but it's sort of okay if it's heavily flavoured.
I also rather go hungry than eat a bowl of cereal because it's boring, unfulfilling, and it sort of incorporates the airy textures which I don't like.
