Garlic and onion skins, thyme and basil stems, tops and bottoms of zucchini – the list goes on – all add so much flavor to the broth. You save money that you would have ordinarily spent on store-bought stock, and help keep the planet a greener place by allow your waste to dissolve in a pot of simmering water instead of a trash bag on the street.
Combine the veggie scraps, bay leaves, peppercorns, and water in a large stock pot. Bring to a boil.
Turn the heat down to low and simmer for 2 to 6 hours, until deeply colored and flavorful. Set a fine mesh sieve over a large bowl. Pour the stock through the sieve. Discard or compost remaining solids (many will have dissolved). Store the stock in an airtight container in the fridge or freezer until the next time you make soup.
