Chapter Summaries

Andrew’s experiment revealed that his process could turn wood into a food-producing mixture, prompting Dumbledore to have Professor Sprout teach him Food Magic. Andrew learned how to make batter into bread or cakes, and Dumbledore left to fetch Filius and supplies before Andrew tried the spell.

• Snape identified Andrew’s black solution with a simple Scarping Revealing Charm, and McGonagall and Dumbledore discovered that Andrew had added no magical concealment or protection.
• Dumbledore asked Andrew to repeat the experiment, and Andrew used kitchen wood to produce another basin of the mixture.
• Snape realized the solution could mean an almost endless food supply, and Dumbledore asked Andrew about his progress with charms.
• Dumbledore brought Sprout to teach Andrew how to use Food Magic to turn batter into bread or cakes.
• Andrew practiced under the professors’ scrutiny and learned the spell in less than half an hour, but Dumbledore stopped him before he tried it and went to fetch Filius and supplies.

Andrew demonstrated the Orcish Imagination Process to Dumbledore and the gathered professors, who confirmed that it could turn ingredients into food. Professor Sprout made an improved cake for everyone to taste, while Andrew’s first cake was made permanent and set aside for the Trophy Room.

• Dumbledore returned with Snape and asked Andrew to repeat the Orcish Imagination Process, while the professors watched.
• Flitwick and Sprout used the Scarping Revealing Charm and confirmed that Andrew’s result was food, despite its poor quality.
• Andrew Transfigured his first mixture into a black, rough cake, and Flitwick made it permanent at Dumbledore’s request.
• Sprout combined the remaining ingredients, removed impurities, and shaped the mixture into a cake divided into seven portions.
• Andrew and the others tasted their portions, and Andrew found his coarse, bark-like cake sweet and unmistakably edible.

Andrew revealed that he would publish the food-producing Transfiguration process and its prerequisite spells for free, and Professor McGonagall arranged for him to document the work. Dumbledore then ordered Andrew to pause his experiments after finishing the thesis and study Latin and laboratory procedures first.

• Professor Sprout left to preserve a copy of the grass-bread memory, Professor Flitwick took the Glass Basin, and Professor Snape accepted one-fifth of the enzyme.
• Professor McGonagall expressed concern about how quickly Andrew had achieved the breakthrough.
• Andrew told Professor McGonagall and Dumbledore that he would publish the spell and its prerequisites without charge rather than let the school profit from food production.
• Professor McGonagall told Andrew to divide the enzyme, submit a thesis to Transfiguration Today, and begin writing the next day.
• Dumbledore told Andrew to finish the thesis, suspend his experiments, study Latin, and receive laboratory-procedure tutoring from Professor Snape.
