Why does my ice cream leave a waxy texture on the roof of my mouth?
Try heating the cream and milk to just below a simmer. Right before adding the milk mixture to the yolks whisk the sugar, vanilla, and eggs together. Pour the hot milk mixture into eggs very slowly. It's best to strain it through a fine strainer. If you use vanilla bean make sure to add it after straining it. Let cool a little before putting it into the fridge. It should be cold before making the ice cream. It's not necessary to fully temper ice cream base like crème anglaise.
