In a medium sauce pan combine 1 cup heavy cream and 1 cup milk until it starts to bubble around the edges – do not let it boil!
Meanwhile, in another bowl whisk together egg yolks and sugar until pale and fluffy.
Remove milk and cream from the heat.
While whisking, pour 1/2 cup of the cream liquid into the egg yolk/sugar mixture. Repeat with one more 1/2 cup of liquid. Whisk continuously so the eggs don’t cook!
Dump that mixture back into the pan with the remaining cream and milk and heat for a few more minutes until you can draw a line on the back of the spoon when coated with the mixture.
Remove from heat and strain into a bowl.
Add vanilla and a pinch of salt and stir to combine.
Add strawberry puree and stir to combine.
Place bowl inside a larger bowl and fill the sides with ice and let the mixture come to room temperature, stirring every so often (for about 1 hour)
Cover with a lid or plastic wrap and refrigerate for 4 hours or overnight for best results! (at this point you could also distribute this into creami pints if you’re using that as your ice cream machine!)
