You can strain fruits and vegetables by adding juice to the juice you already have.
Fruita, for instance, is a popular product for people who need to supplement their juice.
To make your own juice, start by blending up about one-quarter cup of fruita in a blender.
If you are not using a blender, blend the juice until smooth.
Then add the juice to a container and stir it to make sure the juice does not get soggy.
