Which fruit is in the picture?

An oroblanco or sweetie is a sweet seedless citrus hybrid fruit similar to grapefruit. It is often referred to as oroblanco grapefruit.

Oroblancos are either round- or oval-shaped with a thicker rind than grapefruit. When eaten, an oroblanco lacks bitterness associated with grapefruits and is rather sweet, even when the outer peel is still green, but the white membranes separating the fleshy segments are bitter and usually discarded.

Oroblancos are available from September through December. They may be peeled and eaten like an orange — by separating into segments — and are often eaten at breakfast.
