The Tarocco is mild in color both on the surface and the interior, but very sweet. It has red veins inside but remains light in color. Hints of berry mixed with a mild but recognizable tartness make this a fabulous citrus experience. The Moro is deep blood red inside with a strong raspberry undertone. Both varieties are easy to peel and have few seeds. Available from November to May from various growing regions in California. Pick fruit that is heavy for it's size. This fruit normally has a fair give to it.
