Nice knowing a friend interested in chocolates. Are you a Filipino? Yes we have been making the old style chocolate "tableya" in our own dialect since the 80's. It was handed down to us by my father, born in Pila, Laguna where tsokolate is a native fare. We have acquired a 2nd hand 5kg capacity roaster from Japan a stone melangeurs from India to improve our quality. It seems it did.
