Tangor

The tangor is a citrus fruit hybrid of the mandarin orange and the sweet orange. The name "tangor" is a formation from the "tang" of tangerine and the "or" of "orange." Also called the temple orange, its thick rind is easy to peel and its bright orange pulp is sour-sweet and full-flavoured. The name "temple orange" is taken from the name of citrus magnate William Chase Temple. (Wikipedia)
