Seriously the answer cannot be too complicated.





I have googled and Binged and Yahooed and now I am confused.

Age?

Do you want to know the diiference in a new potato and a regular potato?

Holy shit there are some goofy looking taters.

I see a lot of potatoes that look like Nixon.

IIRC, new potatoes are small and round.  Normal potatoes are the kind that get turned into baked potatoes.

Wise Geek sez...
One popular trend in cooking is the harvesting of young or immature vegetables, as in the case of very young peas or baby corn kernels. Immature potatoes harvested during the spring or summer are called new potatoes, or sometimes creamers or fingerlings. New potatoes are not a separate variety of potato, but younger versions of other varieties.

The skin of new potatoes is generally thinner and flakier than the skin found on older potatoes. For this reason, new potatoes are rarely if ever peeled before cooking. Restaurants and cafeterias use special machines with rotating abrasive wheels to remove some of the peels from new potatoes, but home cooks may just want to wash the new potatoes thoroughly and keep them unpeeled.

 I have one that looks like obama.

Potatoes picked before fully matured.
