I'm not sure whether you mean horse flesh flavored ice cream, caviar flavored ice cream, etc., or those things independently and then the squid ink ice cream ;P
I'm not that big into meat, and I'd hate the idea of eating a horse since they're such noble creatures, so that's out.
Caviar I've had, I didn't like it, it was saltier than ocean water
Blue Cheese I've had tons of times, it's not so great by itself, but it's good in certain salads. Even though it's literally moldy cheese. =P
So, squid ink flavored ice cream it is. Though I'm scared. =P
