Grandma'S Macaroni Pudding - cooking recipe

Ingredients

1 cup macaroni
5 eggs
600 ml milk (or substitute cream if decadent!)
3 tablespoons sugar
1 teaspoon vanilla extract
1 pinch salt
ground nutmeg

Preparation

Cook the macaroni in salted water and drain.
Whisk remaining ingredients together, add macaroni.
Pour into ovenproof vessel of your choice (I use a Pyrex rectangular dish)sprinkle nutmeg on top and bake for about 45 minutes at 170\u00b0C This time can vary depending on the quantity of custard and macaroni. And of course on how firm or soft you want it to set. Note that I tend to just watch the custard, and take it out of the oven when it's set. Depends on how wet the macaroni was, how big eggs are, if I sub cream inches.
I've made some changes to this recipe (added some eggs, increased heat and cooking time, as well as upping sugar) so hopefully people meet with more success. I posted the recipe as written in Grandma's cook book, but have since experimented and found she must be like famous chefs, never record the actual recipe, in case some one else copies!
Hoping for feedback about how this version goes.
