Goober is a combination of peanut butter and jelly in a single jar.
It is sold in North America, the UK and Singapore and is named after a North American name for the peanut, which comes from the Gullah word for peanut, guber. Goober was introduced by The J.M. Smucker Company under the Smucker's brand. It consists of alternating vertical stripes of peanut butter and either grape or strawberry flavored jelly, or chocolate.
A similar product is sold by Kroger under their name, the Ralphs brand name and as Yipes! Stripes! under Kroger's Disney Magic Selections label.
