JAM ROLY-POLY

Steps:

• Pulse flour, sugar, baking powder, and salt in a food processor until combined. Add butter, and pulse until pieces are no larger than peas. Add milk; process until a soft dough forms. Place dough on plastic wrap, and pat into a rectangle; wrap in plastic. Refrigerate 30 minutes.
• Preheat oven to 400 degrees. Place a roasting rack in a large roasting pan. Butter a 21-inch piece of parchment paper; set aside. Bring a large pot of water to a boil.
• Turn out dough onto a lightly floured surface. Roll out to slightly thicker than 1/8 inch. Cut into a 15-by-12-inch rectangle. Spread jam over dough, leaving a 1-inch border. Sprinkle chocolate over jam if desired. Fold short sides of dough in by 1 inch. Roll lengthwise to form a cylinder, brushing off excess flour. Pinch ends and along length of cylinder to seal.
• Place seam side down in center of buttered side of parchment. Bring long sides of parchment together at top, and make a 1/2-inch fold. Fold over again, and seal. Tuck ends under. Repeat with foil, folding sides together and twisting ends.
• Place wrapped cylinder on rack in pan. Add enough boiling water to come about 1 1/2 inches up sides of pan (water should not reach pudding). Transfer to oven; bake 1 hour, adding boiling water occasionally to maintain level. Loosely tent with foil; bake until an instant-read thermometer inserted into center of pudding registers 180 degrees, about 30 minutes.
• Transfer pudding to a wire rack, and let cool 20 minutes. Remove foil and parchment, and slice. Serve warm, with creme anglaise if desired.
