Heat 8 eggs (some may want to use up to 16 per gallon) in a pan until reach 170 F (don't want to cook the eggs only have at that temperature for a couple of minutes to kill off any pathogens). Remove from heat.
Add ~1.5 cups of sugar, nutmeg, cinnamon, vanilla... and dissolve into the eggs. (Don't use ground cloves as the temperature will not get hot enough to dissolve and it was a little gross:-).
Cool the mixture down before adding to the a finished, cooled gallon of fresh ProBiotics. I sprayed some water on the bottom of the pan to cool quicker. You don't want to kill the ProBiotics by pouring in the egg mixture while it is hot. I also used whole milk to make the ProBiotics so it was very creamy, thick, and rich.
Cool the finished mixture a little more if desired. You can sprinkle a little cinnamon on each glass with maybe a shot of whip cream if desired. Enjoy!
