1 recipe pate a choux
1 egg mixed with 1 T water, for egg wash
Oil, for plastic wrap
2-1/2 pints ice cream
10 oz semisweet chocolate, chopped
½ c cream
2 T corn syrup
Preheat oven to 425 with a rack in the center. Line two unrimmed sheets with parchment paper or silpats.
Make pate a choux batter, and fill a pastry bag fitted with ½ inch tip and pipe 2-inch rounds that are about 1 inch high onto baking sheet at 2-inch intervals. Using your finger, rub egg wash over entire top and flatten the tips being careful not to let it drip onto sheet.
Cover one sheet with lightly oiled plastic wrap and place in refrigerator. Transfer the other to the oven and bake 10 minutes, then reduce heat to 350. Bake until puffs are golden, about 15-20 more minutes. Turn off oven and prop door open slightly to let steam escape. Allow to dry out in oven, about 15 minutes. Transfer to a wire rack to cool completely.
Raise oven heat back to 425 and repeat for remaining batch.
Scoop out 26 balls of ice cream and place on parchment lined baking sheet. Let ice cream reset for 20 minutes.
To make chocolate sauce, place chocolate in a bowl. Combine cream and corn syrup in small saucepan and bring to a boil. Pour over chocolate and let sit 5 minutes. Stir to combine. Allow to cool slightly before serving, or store in refrigerator up to 1 week and reheat over low heat before serving.
Cut each doughball in half horizontally and fill with a scoop of ice cream. Place two halves on each plate and top with warm chocolate sauce.
