My current favorites include:
Straight up freshly squeezed oranges, nice and pulpy.
Carrot, Orange and Ginger juice (ratio 2:1, oranges:carrots)
Orange and Banana smoothie. Juice 2 or 3 oranges; pour the juice of one orange into blender, add banana and blend; stir in the remaining orange juice. In my blender it gets a bit too frothy if I blend all the orange juice with the banana.
Any favorites that you recommend?
