The carrots are peeled and chopped. Keep the apple's skin on while you chop it. Orange peeling.
Blend the carrots, orange, apple, salt, and water in a food processor. Mix on high until a puree and juice are produced.
To remove the pulp, strain the juice through a nut milk bag or a fine mesh sieve. Delete the pulp (or use: see ideas above). Add the fresh lemon juice and stir. Drink right away, or wait until it's chilled.
