INGREDIENTS

4 large egg yolks

2 cups heavy cream

¼ cup granulated sugar

2 tablespoons espresso coffee beans, cracked in a mortar with a pestle or otherwise cracked, plus 4 whole beans for garnish

Boiling water

3 tablespoons finely packed brown sugar

Ice cubes

DIRECTIONS

1. Preheat the oven to 325° F. 

2. Have ready four ¾ cup heatproof ramekins and a baking dish just large enough to hold the ramekins.

3. In a large bowl, whisk together the egg yolks until thickened, about 2 minutes. 

4. In a saucepan over medium-high heat, combine the cream and sugar, stirring until the sugar melts, and small bubbles appear around the edges, 3 to 4 minutes. Remove from the heat, add the cracked coffee beans and let stand for 10 to 15 minutes. The longer the mixture stands, the more pronounced the flavor will be. Taste after 10 minutes. 

5. When the flavor is to your liking, strain the mixture through a fine-meshed Chinoise or other fine-meshed wire strainer into a bowl. 

6. Gradually whisk the cream mixture into the egg yolks and strain again. 
Fill each ramekin to within ¼-inch of the rim. 

7. Place the ramekins in the baking dish and pour boiling water around them to reach half way up the sides of the ramekins.

8. Place in the preheated oven and bake until the custards are set but still a bit jiggly in the middle and a thin, slightly golden skin has formed on the top, 35 to 40 minutes. 
Transfer the baking dish to a wire rack and let the custard cool slightly. Remove the ramekins and let them cool to room temperature. 

9. Refrigerate until well chilled, 3 to 4 hours and up to overnight. 

10. When ready to serve, preheat the broiler. Place the brown sugar in a small sieve, and using a spoon, push it through sieve and evenly sprinkle the tops of the custards with the sugar. Return the ramekins to the baking dish, pour cold water around them and add several ice cubes to the water. Broil until the sugar melts and caramelizes, 2 to 3 minutes. Alternatively, use a small kitchen torch sot caramelize the sugar.

11. Remove the custards from the baking dish and transfer them to a wire rack and let the custards cool until the surface hardens, about 10 minutes. Serve immediately, each ramekin garnished with a coffee bean.
