You don't have to spend a fortune on packaged orange juice. Or worry about which brand is healthiest and least processed. Just pick up a bag of fresh oranges -- opt for Valencias or other low-acid varieties -- and take them home to make your own juice. It takes a little work, but getting your orange juice straight from the source is the freshest way to go.
Inspect each orange carefully. The fruit should be firm and smell fresh. Discard any with moldy spots or soft areas.
Scrub each orange under running water to prevent contamination of your clean knife and cutting board by a dirty rind.
Slice each orange in half at its equator, leaving the stem end at one pole. This cuts all of the fibrous wedges in half, making it easier for the juice to come out.
Press each orange half onto the citrus juicer. Twist the orange on a manual juicer. If you're using an automatic citrus juicer, hold the orange in place firmly and turn on the machine.
Juice each orange until all that's left is the fibrous insides. You should see the white parts of the insides of the peel.
Repeat the juicing step for each additional orange half. Enjoy your freshly squeezed orange juice right away, or store it in the refrigerator.
Using a Blender
Wash each orange and check each one for signs of spoilage. Discard inedible fruit.
Peel the rind of each orange and pull apart the wedges. Cut wedges from larger oranges in half.
Add a small amount of water to your blender pitcher. Put some of the orange pieces inside. You'll only want to fill it about one-third of the way to start.
Cover the blender pitcher and turn it on to a medium setting. If it's having a hard time, pour in a bit more water. Once everything blends, continue adding orange pieces a few at a time.
Strain the pulpy juice through a strainer or sieve to remove some of the seeds and pulp. For a thinner consistency, use a fine strainer or line your strainer with cheesecloth, to remove the majority of the pulp.
Pour the juice into glasses and enjoy it immediately -- or store in the refrigerator for later.
