Watermelon and orange
This combination of Vitamin C enhances immunity and is great for hot days. How do you make juice? Simple.
Beat half watermelon (peeled and seeded) in the blender with a glass of orange juice. Strain and serve ice cream.
Depending on the taste of oranges, you can add sugar or not. Try to buy ripe oranges, because they are sweeter and the juice does not need sugar, so it gets healthier.
