5.5 quart Dutch oven and simmered the broth for almost two hours before adding the seafood. It was redder looking than the picture and quite tomato-y tasting. I did use the Pomi tomatoes. I added an extra 1/2 cup water, but I think it would have benefitted from a cup of clam juice and would make it again with that addition instead of extra water. I used 3/4 lb of scallops as that's how I had them packed, and 3/4 lb each of shrimp and cod. Served with a Caesar Salad and crusty bread.http://www.myrecipes.com/recipe/slow-cooker-cioppino
