Spray an oval slow cooker with non stick spray. We are using an oval slow cooker to ensure the center of the custard sets before the edges burn.
In a medium sized bowl add the eggs, sweetened condensed milk, whole milk, vanilla and salt.
Whisk until smooth, this will only take a minute or two.
Pour the egg mixture in to the slow cooker.
Cover and cook on LOW for 2 hour and 45 minutes. The custard will be set in the middle.
Remove the slow cooker insert from the heating unit and place on a wire rack to cook. Cool for an hour. Sprinkle the entire custard with nutmeg. Slice. Serve warm or cold
Notes
The ideal way to store custard is by covering it with plastic wrap (or placing in an airtight container) and keeping it in the refrigerator.
Ground cinnamon and ginger are tasty flavors of the season that can be sprinkled on top as well.
