This is a basic New England style seafood stuffing using Ritz crackers that can be used to stuff mushrooms, seafood, or even as a topping for baked fish. I incorporated some of my favorite ingredients from different recipes. I've included a recipe for stuffed mushrooms that can be prepared and refrigerated for up to 2 days before, or frozen for up to a month, since the mushrooms are pre-cooked. Using small mushrooms, this recipe will fill about a pound of mushrooms, about 20-25 if you use small appetizer-sized ones. You can include the chopped mushrooms stems if you like, but I usually leave them out, and use them another time. Time is for making the stuffing only, since the mushrooms have some variations. Amount is approximately for stuffing.
