Vegetarian stock

I don't know whether it helps or hurts that I don't much like vegetarian broth - no brand or form of it canned is even edible, so far as I am concerned.  Ugh, what do they put in it?  So  I am trying to make it from scratch.  We've had several batches, all different, all okay, none perfect, but we're getting closer.

Ingredients.  We decided against the turnip.

One rule: don't overcook, because most overcooked vegetables, even seasoning vegetables, taste sour and awful. (There are exceptions; some green vegetables develop a different and much better taste after being cooked for an hour or more.)

Another rule, as I am learning, is that what meat contributes to good stock is an abundance of the flavor called "umami", a Japanese word meaning "deliciousness", which in its pure form is found in monosodium glutamate.  If a veggie stock is going to satisfy, umami must be included from vegetable sources.  Ingredients high in glutamates include ripe tomatoes and mushrooms, especially dried shiitake mushrooms.  Also high in glutamates are potatoes, sweet potatoes, carrots, and peas. Thus, veggie stock will be more satisfying if it contains, at least, tomato paste, mushrooms, carrots and peas.  The more of those other ingredients included in the soup,  the more satisfying the broth will be.  With glutamate- rich foods as a base and liberal inclusion of the standard seasoning vegetables, we can produce a stock both satisfying and tasty.

Start with this:

Onion
Celery
Garlic
Carrot
Green pepper
Mushrooms

Dice and saute vegetables in batches to bring out the flavor, and when softened, place them in a cooking vessel (stockpot, crockpot, microwave- safe container, hotpot) about twice the volume of the vegetables you've sauteed.

Seasoning Vegetables

Then add:

Tomato paste
Green peas
Parsley with stems
Salt if wanted

Fill pot 3/4 with water

Cook on High until hot, then reduce to Low and cook until vegetables are just done.

Strain out as much of the broth as you want to reserve, leaving enough broth with the cooked vegetables so that with the addition of some fresh items you can serve it as Vegetable or Minestrone soup.

One pint of stock will fill a 16-cube ice tray,  giving you frozen stock measured roughly in ounces for use in quick "little soups" or in other dishes.

Vegetarian Broth

Note:  Other ingredients to consider for veggie stock are "kombu", a seaweed used in Japanese cuisine, soy sauce, and Chinese cabbage.  All these will undoubtedly increase the "deliciousness" of your stock, but whether the flavors are appropriate will depend on what you intend to do with the stock.
