Turkish Profiteroles vs Classic Boston Cream Pie

Both desserts pair a vanilla pastry cream thickened with cornstarch and egg yolk with a chocolate topping, yet they put the shared eggs and dairy to very different uses. The Turkish profiteroles bake eggs into golden, puffed choux shells, fill them with a cream lightened by folded-in whipped cream, and finish with a warm cocoa sauce cooked from milk. The Boston cream pie beats its eggs with sugar into a fluffy sponge, enriches a yolk-heavy pastry cream with butter, and blends cream with chopped chocolate and corn syrup into a smooth glaze. One is airy and saucy, the other a chilled, layered slice.
