Why does my ice cream leave a waxy texture on the roof of my mouth? I made a batch of ice cream using the following as the base:
1 pint cream,
1 cup milk,
4 egg yolks,
½ cup sugar,
2 tsp vanilla extract

I simmered that until just boiling and then cooled it for a few hours before finishing it up in my ice cream maker for 20min.

I've used this base a few times and add different fruit and spices based on what I want to make.

The problem I'm having is the ice cream leaves a waxy coating on the roof of my mouth. It still tastes great, but the coating is unpleasant. Should I use a different recipe to start with? Am I doing something wrong when I make it?
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.
