Potato

Potatoes are a food item that can be planted and consumed. When consumed, they restore half a hunger point. Potatoes can be farmed and harvested on farmland, the same way as farming Wheat and Carrots. When farmed, they will take 4 stages to grow rather than the normal 8 for Wheat. Fully grown potato crops drop 1 to 4 potatoes and have a 2% chance of dropping an additional Poisonous Potato. Currently, potatoes are only found in the Creative inventory, or as a rare drop from zombies.

Chips
Jeb_ Tweeted that he will add chips when %100 of the community agrees on what they look like. It is unknown if this was a joke or not.
