Bitter Chocolate Custard

Directions

1. 1
   Melt the chocolate and praline separately in glass bowls in the microwave, using 30-second bursts.
2. 2
   Stir together until smooth, then fold in the feuilletine.
3. 3
   Roll the mixture between two sheets of parchment to a little less than 1/4 inch thick.
4. 4
   Clean up the edges and slide onto a baking sheet.
5. 5
   Freeze for at least 2 hours.
6. 6
   Set up an ice bath in a large bowl.
7. 7
   Put the chocolate in a glass bowl and microwave for 30 seconds.
8. 8
   It wont be completely melted.
9. 9
   Spoon 3 tablespoons of the milk into a small glass bowl.
10. 10
    Sprinkle the gelatin over the surface and set aside.
11. 11

    Bring to a simmer over medium heat.
13. 13
    Whisk the eggs and sugar in a medium bowl until pale yellow.
14. 14
    When the milk mixture is simmering, slowly add about 1 cup to the eggs and whisk for about a minute to temper them (keep the pan off the heat while you do this).
15. 15
    Scrape the eggs back into the saucepan and cook, stirring pretty much constantly, until the mixture reaches 180F.
16. 16
    Keep an eye on the color of the foam on the surface; when it turns the same color as the mixture, youre very close to the right temperature.

    Line eight 2 1/4-inch tart rings with acetate or parchment, making a collar, and place on a baking sheet.
27. 27
    Cut eight 2 1/4-inch disks of devils food cake and place in the bottom of the molds.
28. 28
    Cut 2-inch disks of the pistachio-chocolate crunch and set on top of the cake.

    Alternatively, you could serve the bubbles next to the desserts.
