If you really want to save 
money and eat healthier foods, make your own stock! Most bouillon cubes or even organic pre-packaged stocks contain a lot of salt, as a preservative. If you use the rule-of-thumb that a packaged food shouldn’t have more milligrams of sodium than it does calories, you might be disappointed when you read the label of your favourite prepared stock.
Stock-making is simple. One trick I learned from Ken Kostick. He suggested that as you peel carrots, onions, take the stems off aromatic herbs, and so on, that you should put them in a zipper bag in the freezer. (Give them a rinse first!) When the bag is full, it’s time to make stock. Sometimes I roast this mixture, other times I just use it “as is”. I like to use one of those pasta pots with the strainer-type liner, just to make it extra easy.
Put the vegetables in the bottom of the pot. Cover with cold water. If you haven’t used too many herbs during the week (really?) add some dried herbs – tarragon is nice, or savory, bay leaves…or some minced ginger is good, too. Bring this mixture to the boil on top of the stove and then turn down to a simmer, so it’s just slowly bubbling along. Let it simmer while you watch a favourite television show, or do a load of laundry, whatever. Check now and then so it doesn’t boil over.
Let it cool, and strain or if you use a pot like I do, lift out the liner. Package it up in convenient sized containers and store in the freezer. If you make some up in ice-cube trays, you can use those for times when you just need a tiny amount.
More on meat and fish stocks, another day. If you don’t feel like using this stock today…save it til tomorrow, throw in some cooked beans or chickpeas, onions, and whatever vegetables take your fancy. Simmer for half an hour or so, add a handful of whole-wheat pasta and simmer til tender and voila…delicious vegetable soup!
