Preheat the oven to 325°F.
In a medium mixing bowl, beat the eggs slightly with a hand-held mixer. Next, add the sugar, salt, and vanilla. Beat just until fully incorporated. Set aside.
Add the cold milk to a medium saucepan. Heat the milk over medium-high heat, stirring frequently. Do not boil the milk; you only want to scald it. The milk is scalded when small bubbles appear around the edge of the saucepan, or the temperature registers 180°F.
Slowly drizzle 1 cup of the scalded milk into the eggs, whisking the eggs quickly the entire time. Then, slowly pour the remainder of the milk over the egg mixture, whisking constantly.
Pour the custard into six 8-ounce Ramekin cups (or something similar in size)
Place the cups in a 9x13-inch baking pan, and fill the pan halfway with water.
Bake for 50-60 minutes. Test for doneness by inserting a knife in the center; if it comes out clean, the custard is done.
Allow to cool slightly, then sprinkle generously with nutmeg (strongly recommended).You can also serve with fresh berries. Eat the custard warm or chilled. Store custard in the refrigerator and eat within three days.
