What does "reserving liquid" mean?

Question

In my recipe for vegetable soup, it says "Drain and set aside, reserving liquid". How do you reserve the liquid?

Answer 1

Strain the liquid from your soup and set it aside before you continue to cook everything else.  Vitamins in the liquid is good and liquid is where your good taste comes through.

Answer 2

It just means to save the juice you drain off, usually to be added back later..

Answer 3

You save that liquid to use in another part of the recipe

Answer 4

You drain off the juice and then you add it back later on  

Answer 5

Drain the liquid from the can into a cup and set it aside to be used later in the recipe. Do not ever drain this down the sink drain. If it isn't to be used in this recipe, put it in a freezer container and stick it in the freezer til next time you go to make soup. You can defrost all the liquids from canned veggies or those veggies you cooked in water for Vegetable Broth.

A lot of the vitamins in veggies are water soluable and are in this liquid. Draining down the sink is totally wasteful of the vitamins.
