I used to HATE cilantro. Made me gag (my dad too), and if even a smidgen found itself into my food, I couldn't eat the whole dish. My mom had to change all her recipes to take out the cilantro (which she loved). My cat at some point found some neighbor's cilantro plant (WHO GROWS CILANTRO?!!?!) to rub in for a few months and I couldn't stand to be near him.
Then, at some point, I liked a LITTLE bit in salsa, and then I could stand it. And now I actually like it. Weird.
