Add in sugar and stevia and beat until sugar is dissolved.
Combine milks, salt, and nutmeg in a saucepan, and bring the mix to a boil, stirring occasionally.
Remove the pan from the heat, and slowly mix it into the egg/sugar mix, stirring continuously.
Return everything to the pot, stirring continuously, and heat until temperature reaches 160 degrees, or about 1-2 minutes (don't go longer or it will curdle). I usually turn off the heat after about 30 seconds and let the pan sit there for another minute or so while stirring.
Add in the vanilla.
Chill and serve!
