In a sauce pan combine the milk, cream and 1/2 cup of sugar. Cook until sugar dissolves.
In a separate bowl beat the eggs and 1/4 cup of sugar until they become thick and pale yellow.
Next take 1/2 cup of the warm milk mixture and beat it into the egg mixture.
Slowly add the egg mixture into the pan with the milk mixture.
Continue cooking over low heat until thick and the mixture coats the back of a spoon. About 7-10 mins.
Pour mixture through mesh strainer, stir in vanilla extract and cool overnight in the refrigerator.
