2. 2

   Toast in the oven for 10 minutes, or until fragrant.

3. 3

   Let cool for about 10 minutes (or until cool enough to handle but still warm) and rub the nuts in a dish towel to remove most of the skins (some will cling and thats O.K.

4. 4

   ).

   In a medium bowl, melt together gianduja paste and butter, either over a pot with 1 inch of simmering water or in a microwave.

6. 6

   Stir occasionally.

9. 9

   Place egg yolks in a small bowl.

10. 10

    Slowly whisk in a 1/4 cup of the hot half-and-half mixture, whisking constantly and carefully so as not to scramble the yolks.

13. 13

    If you see curdled clumps in your custard, pass through a fine strainer before continuing.

14. 14

    While whisking constantly, slowly pour the warm custard into the warm melted chocolate (you want the two mixtures to be the same temperature).

    Cover custard and transfer to the refrigerator to chill for at least 2 hours.
