I follow your flavor claim, but lose me on the texture bit. They feel veeery similar tbh.
But i cannot STAND white chocolate. Its way too sweet for me, and it overall tastes too much like milk. So much so i usually get 70% cacao content, which would probably be too bitter for your tastes.
I only eat Lindt 70% chocolate. It's absolutely perfect and I cant stand anything higher or lower in cacao percentage. And the Lindt brand is extremely smooth. So good. And it's relatively healthy with more fat and protein than carbs, so it satisfies me after about two squares.
