A lot of people are having trouble with food. I live this game so much Ive played it many times. If all your blackberries are gone, you should hurry. I suggest doing this before you have harvested all your blackberries. The rubble next to the hard fruits is what u need to work on. U may need to upgrade your science or technology first. Drag several villagers onto the pile. It will take them a long time to clear all the rubble. Once you clear the rubble, take that pile of rocks and drag a villager to it then they will put it in the fire. Get four rocks into the fire. There is a palm tree thing next to the blackberry bush once u have four rocks the villager will place the leaves on the pit and then shake down the fruit and it will cook!
