Step 2

Preheat the oven to 300°F. Find a large casserole or deep baking dish that fits all four molds.

Step 3

Heat the milk with 1 1/2oz sugar and the split vanilla pod until just warmed (not boiling). Remove the vanilla pod. Meanwhile, gently stir the egg yolks and whole eggs together, taking care not to incorporate air.

Step 4

Pour the warm milk mixture into the egg mixture, stirring gently. Pour into the prepared molds.

Step 5

Place the molds in the casserole. Boil water and carefully pour into the casserole to create a bain-marie without splashing the custard. Bake on the middle rack for 35–40 minutes until a toothpick comes out clean.

Step 6

Cool in the molds for 1 hour at room temperature, then refrigerate overnight. To unmould, gently release the rim and invert onto a serving plate. Serve with dulce de leche on the side.
