Sara's Vanilla Pudding

I just stole this recipe from my friend Sara's blog!  It was so yummy!

Mix in a saucepan:
2/3 cups sugar
dash of salt
2 1/2 Tbsp. cornstarch
1 Tbsp. flour

Gradually stir in:
2 cups milk (1%-whole)
1 cup sweetened condensed milk

Cook over medium to medium-low heat, stirring contstantly--and I mean constantly! Mixture will thicken. Boil one minute; remove from heat.

Slowly stir half of the mixture into 3 beaten egg yolks in a separate bowl. Then pour egg mixture back into the pan and boil for one minute, stirring constantly. Remove from heat.

Blend in:
1 1/2 tsp. vanilla
1 Tbsp. butter
Cool. Serve with vanilla wafers. :)
