10 slices of duck prosciutto (or any other prosciutto), very thinly sliced
Method
1
Two to three weeks ahead, soak the prunes in Armagnac, checking frequently and adding more Armagnac if necessary (prunes absorb it quickly).
2
Place the duck terrine in the bowl of a food processor. Pulse until smooth and spreadable (do not overpulse). Reserve 10 tablespoons for the Gascogne sushi and put the rest in a pastry bag fitted with a large tip.
3
Pipe the foie gras into prunes (use your finger to make the center larger) to create French kisses.
4
For Gascogne sushi, spread 1 tablespoon of mousse onto each duck prosciutto slice and roll up.
