It took me a long time to replicate my mother in laws which was a back of the box recipe from way back when. She would put about 1/3 of the noodles down and sprinkle with Lawry's and cheese and pats of butter. She would repeat the layers and then pour a can of evaporated milk over the top. The secret to her recipe was crushed Saltines and a few pats of butter to make it crunchy on top.
