Tap Lightly a Sweetened Bread

Tap lightly a sweetened bread--do it again--you pastry chef, you! Prepare for my anabolism one such delicacy with all the speed you can muster. Tap it lightly with an open hand, perforate the upper crust with a sharply pointed instrument, inscribe thereon the twentieth alphabetic element, and, finally, insert it into the enclosed baking chamber in the stove for myself and Thomas to devour.
