Have you ever trained/tricked yourself into liking a food you hated at first?
I've done this a few times just to see if I could. I used to gag at the sight of ranch dressing all throughout my childhood but when I was in college I just forced myself to eat it on stuff and told myself that it was good...and surprisingly it worked!
Right now I'm working on liver, lamb and stinky cheeses. I know a lot of people really love these things and I really want to see what all the hype is about. I hate the feeling that I might be missing out on something because my palette hasn't developed enough.
i've tried forcing myself into liking sushi, but i think it's more of a sensory issue than a taste thing. it's never taken. i never used to like mashed potatoes but forced myself to give it a shot when i began cooking for kids (and didn't always have the energy to make two different dinners) - not as bad as i thought it'd be!
Because I didn't grow up eating avocado and cilantro, when I was first introduced to them, I couldn't stand them. Texture and smell really bothered me. Then someone introduced me to bahn mi, and immediately fell in love with the flavor cilantro imparted. Been a fan ever since. I forget how I got to like avocado, but I really love it now.
I learned to like dishes w/ cumin. I used to hate it, though it smelled like BO (which it still kind of does), but now I enjoy the smokey flavor you end up with.
Alas, I have tried multiple times to like sushi also. Just can't do it, definitely a sensory thing though, nothing to do w/ the taste (a lot of it tastes good!).
I used to dislike tarragon and cilantro, and now I love them. I started liking cilantro in my mid20s.
With lamb, if you find the flavour too strong, try local lamb, instead of the imported stuff. I've found my local Cdn lamb has a milder, sweeter flavour than the NZ or Australian lamb that is sold where I live.
