Very carefully! I have a homemade recipe from my great grandmother, and it involves a lot!! of eggs (more than a dozen), a lot of milk, vanilla, some sugar and some spices. I can't disclose my family's recipe, but I'm sure a simple google search will yield good results. My family's recipe involves separating the eggs, combining the yolks with sugar, milk,and spices. Bring this mixture to a boil. Then you beat the egg whites into a stiff peaks and slowly fold that into the mix. This yields about 20 servings- but you get the point. This procedure takes almost two hours- so if you can't put the effort into it, go to a nearby dairy or buy a high quality organic brand.
