Whisk an egg yolk and 1 Tbsp of coconut milk in a small dish.
In another deep small bowl mix 5 or 6 gr of a whey powder, 8 grams of cocoa powder, stevia and splenda mix or whatever you happen to use, and a pinch of finely ground sea salt. whisk that all up!
Then, with a rubber spatula mix the egg yolk mixture into the cocoa mixture and blend it all up. It's hard not to lick the spoon and just eat that. But stop yourself so you can indulge in the real goodness that is to come!!
Then, in a small saucepan heat 6 tbsp of coconut milk until just simmering and small bubbles appear on the sides.
Remove from stove and begin tempering the chocolate with the milk by adding 1 tbsp of the milk into the cocoa mixture and mixing vigorously as you do that, combining it all. Then continue to do this tbsp by tbsp, until it's all combined.
Then, with the rubber spatula transfer that all back into the saucepan.
Now here is where you need to be super vigilant! Reduce heat to low and put saucepan back on stove. But making sure to stir stir stir that cocoa mixture. It will seem like nothing is happening. But in 30 seconds to 1 minute it will start to thicken and you will see streaks of the pan on the bottom.
Make sure to continue moving that spatula around the corners of the pan. At the 1 minute mark or slightly less you will see small curds start to form. Immediately lift the pan 4-6 inches off the stove top, but continue stirring the mixture around the pan, getting in all areas as it thickens up.
It may start looking dry on the edges and you don't want this, so lift the pan higher and make sure that the flame is low.
Once those curds start forming at the beginning, when you first start to lift the pan off the stovetop, you only need to do that mixing for about 1.5 minutes. I used a timer at the beginning , but eventually you will know when to stop.
So now, take the pan off the stove and place on counter. Add in the coconut oil or butter, only adding in TWO tsp at a time, and mix it all in before adding in the next 2 tsp. It will be nice and shiny and glossy. Take a whiff. It will smell like a Hershey Kiss.
Put it into a small tupperware, or Tbsp rubber kiss shaped ice cube molds (I didn't have any, and metal molds will work just fine t00), and put it in the freezer for 20 minutes or longer, depending on how hard you want your chocolate gelato. It will be very soft gelato at the 20 minute mark. I actually let it sit in there until it's hard, then let it soften a bit, and eat it like fudge. It literally melts in your mouth, like how Hershey Kisses do, or did, when we were kids.
Notes
You can also put this pudding into the baked nut crust, and put it into the freezer for about 20 minutes, for a frozen tart.
