I recently tried to make date truffle, consisting of Date, cashew, almonds. The center became too soft and does not harden, probably because the dates were soaked in water for too long and there was still water content after draining the dates. I refrigerated the center but its not hardening. Is this because of the high water content, If so is it possible to remove the water?

TIA
