Ingredients
- 1 cup, divided (3/4 cup for caramel + 1/4 cup for custard) granulated sugar
- 1.5 cups whole milk
- ½ cup sweetened condensed milk
- 4 whole large eggs
- 1 tsp vanilla extract
- 2 cups water
Instructions
- 1
Combine 3/4 cup sugar in a small saucepan over medium-high heat. Stir constantly until amber and fragrant, about 4 minutes.
- 2
Quickly pour caramel into a round 6-inch ramekin or small bowl, coating the bottom and sides. Set aside to cool.
- 3
Whisk eggs, whole milk, condensed milk, remaining 1/4 cup sugar, and vanilla until smooth. Pour mixture through a fine sieve into the caramel-lined ramekin.
- 4
Place ramekin in a larger pot or deep skillet. Pour hot water into the pot until it reaches halfway up the ramekin's sides, creating a water bath.
- 5
Cover the pot loosely with foil. Simmer over medium-low heat for 8 minutes, until custard is just set but still slightly jiggly in the center.
- 6
Remove ramekin from water bath and chill in the refrigerator for at least 30 minutes (or serve warm). Run a thin knife around the edge and invert onto a plate to unmold.
