This recipe is from The Essential Ingrediant, and they have a fantastic Bourbon Vanilla Extract! My family love the recipe because although decadant, it is not heavy or too rich, a perfect ending to a meal.
How do you know they are cooked? You will have to use judgement here, do not overcook them, they should woble in the middle but not spill. They DO NOT brown. Make creme caramel the day before you need them - they need overnight to set perfectly and dissolve some of the caramel.
