This is amazing! I put the onions on for 6 hrs then added a can of dark beer instead of the wine. I let that sit overnight. Then completed the soup. Allowed it to cool again for the following day. I had the soup Hot, day old buns sliced and toasted, crocks ready and made up as people were ready. I;ll make this all the time. Janet. VFE
