I have one useful tip!! Put a layer of pasta on the bottom with 4 tablespoons of water then start your layering. The bottom layer helps with serving and it makes it easier!!

Also my god mother always cooks hers a couple of hours before dinner lets in cool in the oven and then cuts it up and re-cooks it!! She said that also helps with serving!! I have never tried it cause I neer know what I am cooking till its to late!! Lol....
