Method
1) Bring milk and cream to a boil in a heavy bottomed pot.
2) Mix egg yolks, sugar and vanilla essence together in a mixing bowl.
3) When milk and cream comes to a boil, pour into the egg yolk mixture and mix swiftly to prevent the egg yolk from coagulating (cooked).
4) You may add in brandy at this moment, strain the sauce and allow to cool (I prefer chilled) before serving this rich Custard Sauce with any dessert you may desire.
