In a medium saucepan, combine heavy whipping cream, milk & sugar, place over medium heat
Cook until simmering
While getting the mixture up to temperature, take egg yolks in a separate bowl and whisk until a little lighter in color
Once cream mixture is warmed, take a ¼ measuring cup and slowly pour the cream mixture into the egg yolk whole while constantly whisking. Repeat 5 times
Once the egg yolks are tempered, slowly pour egg mixture into sauce pan while constantly whisking
Add vanilla, salt and macadamia nuts
Simmer until thickened, stirring constantly
Pour mixture into a bowl with a lid and place in fridge for 8 hours to cool, or longer. This can sit in your fridge for 2 days
Once cooled, churn in an ice cream machine until frozen
Can enjoy like soft serve now or place in a bowl and back in the freezer for a couple hours for a more traditional frozen ice cream
