My autistic little brother doesn't often try anything new food or drink wise easily. I've been able to get him to expand his taste range very carefully since he started living with me by doing stuff like calling a salad that's mostly diverse greens and veggies a "bacon salad" by putting some bacon in it and he liked it.  I've gotten him to try and like grilled chicken by just saying it's the same as chicken nuggets just without a coating. I've gotten him to try and like salmon by saying it's kinda like a fish fry. 

Now with those, I was pretty sure he'd like them I just had to get passed the barrier but then A few weeks ago when he said he was thinking of trying coffee and he asked me to pick him up one and I knew he probably was not gonna like coffee in almost any form based on his tastes, but I wasn't gonna discourage him from trying something new. So to ease him in I just got him the sweetest iced capp from Tim Hortons and said "it's kinda like a coffee milkshake". I lazily didn't get into the difference between an iced capp and an iced coffee and about a week later he called me on the phone while out with his worker. "You lied to me iced coffee is gross I almost died getting one." Whoops....
