I still can't do high-percent dark chocolate. It tastes good for a split second and it's then like every bit of moisture in my mouth, perhaps the whole room, is just sucked dry.
Have always loved dark chocolate. As I got older I liked the darker stuff more. 85-90%. (Fyi 100% is no good. Lol.) Milk chocolate has always been a no for me. Best I can do is tolerate it if the flavor is mostly masked by whatever it is encasing.
