Making thrifty vegetable broth (aka vegetable stock) is easy; it just takes a little thought and planning. At Alandi, we usually make the broth on Friday. All week long, I save clean vegetable scraps in a plastic, cloth or brown paper bag in the frig. This time I had asparagus stalks, watercress stalks, tops and tails of carrots, some Jerusalem artichoke offcuts and the stem and outer leaves of my cauliflower. Often I have broccoli stalks etc.
When you're ready to make the broth, use a stainless steel stock pot. Wash your veggie scraps and put them in the pot. If it's something large, like a cauliflower stalk, chop it up. Look in your vegetable drawer for anything that needs using up. You can wash and add it. If you like, add some dried herbs for seasoning, but you don't have to. And I prefer not to add salt as it's easier for me to salt the final product (soup, risotto etc). Add plenty of water, bring to a boil, cover and simmer for a couple of hours, until the water has a good colour. Strain and store in a screw top glass jar until you're ready to use it as a base for a soup or as called for in a recipe.
