Place the egg yolks in a medium heat-safe bowl. Whisk and set aside.
Place the milk, cream, and sugar in a sauce pan. Heat until sugar is dissolved.
Add the hot milk mixture to the eggs, slowly and gradually, while whisking constantly. It's best to use a ladle for this step. Add one ladle of hot milk at a time so that the eggs don't cook.
Return the custard mixture to the saucepan and cook gently, until thick.
Pour the hot custard over the chocolate and whisk until smooth.
Portion out into small dessert ramekins.
Refrigerate until set, about 2-3 hours.
Top with a dollop of crème fraîche and chocolate shavings.
RECIPE TIPS
The amount and types of chocolate you decide to use is up to you. You can also add flavorings or zests to give these a punch of flavor. (Think orange zest, or a tiny bit of mint extract.)
