Use the recipe as a guide — if you don’t have leeks, onions are fine, though I don’t think leeks lend a special flavor to all stocks, so they are worth buying if you are headed to the store; if you don’t have thyme or tarragon, omit them; etc.
Ingreadient :
1 large yellow onion, quartered through the root
2 large carrots, roughly chopped
1 stalk celery, roughly chopped
1 large leek, washed and roughly chopped, optional
3 cloves garlic, peeled and crushed with the back of your knife
4 sprigs fresh parsley
4 sprigs fresh thyme
1 bay leaf
1 teaspoon coarse salt
1 teaspoon black peppercorns
3 quarts cold water
Direction :
Combine everything in a pot. Bring to a boil, lower the heat, and simmer for 45 minutes.
Let stock cool and strain into clean containers.
Store stock in the refrigerator for 1-2 weeks or in in the freezer for up to 6 months.
