Life is what happens when you’re busy making soup. Bob Sirott and Marianne Murciano tell the WLS AM890 radio listeners in Chicago to buy 4 ingredients to make soup in a slow cooker. Beef shanks, onion, garlic and swiss chard. We demonstrate in our kitchen with a crockpot just how to make beef bone marrow soup. Set the slow cooker for 8 hours and know it will take more than 24 hours before it’s done.
