Frozen Custard

4 c. milk

3 t. vanilla

10 egg yolks

1 1/2 c. sugar

5 c. cream

1 bag mini chocolate chips (optional)

Warm milk and vanilla in a large sauce pan for 15 minutes; DON'T BOIL. Beat egg yolks and sugar together in a large dish until smooth. Slowly stir warm milk into egg mixture until incorporated and smooth. Pour the combined ingredients back into the sauce pan and warm the custard through and thicken without boiling; stir constantly. Let mixture cool and add cream. Freeze as directed. Add the chocolate chips (if desired) and stir at the end of "freezing" when the custard is in soft serve form. Continue freezing or serve soft.
