Foods in general are weird like that: some taste better cooked, others taste better raw, and everything in between. I've heard that raw fish is tastier than when it's cooked (I have no idea how true this is, though, since the only raw fish I've ever had is on sushi, which tends to have so many different ingredients on it that I can't actually tell which taste belongs to which thing XD), but it also comes with its risks because tapeworms and the like, though that's a risk for basically any undercooked meats.
