After reading other comments, I decided to make extra sauce, using 5 cups milk, flour, 5 tblsp flour...and then added a bit of corn starch to thicken more. I also added garlic, salt, white pepper, & nutmeg to it (also gave the spinach mixture same treatment). Then added a whole cup of parmasean cheese, plus a bit of mozz cheese too. I had just enough sauce to cover top!! (thank goodness I made extra!) Extra note: I don't like canned crab (tastes like canned tuna to me), so I used the whole chunk crab, crumbled. My family loved it!! Will def make it again...but will add other seafood too...squid, mahi mahi, scallops.
