Add the eggs and mix well. Scrape the sides of the bowl. Sift all the dry ingredients, and then add them to the egg mixture. Mix on low speed until incorporated. Lastly add the hazelnuts, and mix.
Preheat the oven to 325 degrees F.
Line a half sheet pan with a silpat and sprinkle the mixture onto it.
Place into the oven and bake until golden brown, approximately 15 minutes. Cool completely, place into a food processor and finely grind. In a bowl, mix together 3 cups of the crumbs with the 3 tablespoons of the melted butter.
Press the crumbs into the bottom of a 12-inch round metal cake ring that is sitting on a flat half sheet pan lined with a silpat. Place the pan into the oven and bake for 10 minutes.
Cool by placing into the freezer.
In a saucepan, place the milk, cream, and glucose. Bring it to a simmer. While the milks are heating, place the egg yolks in a bowl with the sugar. Set up an ice bath for cooling the anglaise. Once the milks are hot, whisk some of the milk into the yolks and sugar to temper. Place the mixture back into the pot, and cook until thick enough to coat the back of a wooden spoon. Strain the anglaise into a bowl and place the bowl in the ice bath. Stir to cool down.
Once cool place into the ice cream machine. Spin until firm. While spinning place a metal bowl in the freezer to make it cold. Place the ice cream directly into the bowl and then fold 1/4th of the nutella into the ice cream working quickly.

While heating crack the eggs into a bowl, and place the trimolene along with them. Set up a bain marie with olive oil in it and have an ice bath ready.
Once the milk is hot, whisk together the egg, trimolene mixture and temper the eggs very slowly, and put back on the fire for 30 seconds on low heat, stirring constantly. Strain the mixture into the bain over the oil. Stir to cool.
Pour the mixture into the ice cream machine and spin until firm. Allow it to set up in the freezer for at least 1 hour.
