We make this all the time, varying ingredients depending on how many people it's for - my mom's even adapted it for about 150 folks, and it alway is a bona fida HIT! Our biggest deviation from this recipe is that we heat the oven to 200C and bake for 28-35 min, depending on the strength of the oven and just how browned and crispy you like it. It's utterly delicious either way and positively impossible to put down.
