A New Kind Of Orange Juice

one large grapefruit
one naval orange
one cara cara naval orange (pink on the inside like a grapefruit)

Or 

one cara cara naval orange
one naval orange
one tangerine

Juice all three of these together and you have a wonderful new kind of orange juice.
Both of these taste great. I like to make up new mixtures with whatever I have on hand or whatever is in season.
