In a medium bowl, whisk together your egg yolks and sugar for about 2-3 minutes, until smooth and pale in color.
Whisk in your milk to a saucepan over medium heat. Bring the milk to a simmer and then remove from the heat. Do not boil.
Whisking constantly, add a ½ cup of your hot milk to the yolk and sugar mixture, whisk until combined.
Add the tempered egg yolk mixture back into the saucepan with your remaining hot milk. Mix in your salt.
Whisking constantly, heat on low until the the mixture has thickened enough to coat the back of a spoon. This should take a few minutes.
Strain your mixture into a bowl to remove any pieces of egg that may have gotten accidentally cooked.
Add your heavy cream and vanilla extract to your mix, stir to combine.
Cover your bowl with plastic wrap, making sure to have the plastic wrap touching the surface of the ice cream base so it does not get a skin. Refrigerate for at least 3 hours.
When ready, churn your ice cream mixture in the bowl of your ice cream machine according to your manufacturer’s instructions.
In the last two minutes, add in your chopped chocolate and toasted pecans. Churn until they are evenly distributed.
Spoon half of your ice cream into a shallow container or a loaf pan.
Top with half of the caramel sauce and swirl with a spoon.
Repeat with your remaining ice cream and caramel sauce.
Press plastic wrap the surface of the ice cream. Freeze for at least 4 hours, or until solid.
To serve, allow ice cream to sit at room temperature for at least 5 minutes. Scoop and enjoy!
Notes
Make sure the bowl of your ice cream maker has been frozen for at least 24 hours before making your ice cream.
