Cinnamon Gelato

We have been working on different combinations of ice cream for the last couple of years.  We have the Cuisinart Ice Cream Machine that has 2 bowls.  I keep the bowls in the freezer at all times so we are always ready to go.  I found a recipe that I really liked.  The ice cream gets really thick which I like.  It could be Gelato if I only used milk but I opted for mixing in milk and half and half together.

2 cups half and  half
1 1/2 cups milk ( i used 2% because that is what was in the refrigerator)
2/3 cup sugar
5 egg yolks
1 t. ground cinnamon

Put all of this together in a saucepan that will fit the entire amount.  Turn the heat to medium and whisk the mixture for about 10 minutes.  Yes, ten minutes.  This will make it thick.  It takes that long.  Once it gets thick, remove from the heat and pout into a bowl, cover it with saran wrap pushed down over the mixture and put in the refrigerator for about 8 hours or until really cold.  Then use this mixture in the ice cream machine accordingly.  Once the mixture is done, I generally put it into a Tupperware and in the freezer to use a few hours later.  I served this over blueberry pie.  It was really good.
