Final answer:
The provided text excerpts do not mention Sophie's favorite kind of muffin, and thus it's not possible to determine her muffin preference from the provided information.
Step-by-step explanation:
From the provided text, there is no direct mention of Sophie's favorite kind of muffin. All the excerpts discuss various food items and give a rich description of characters and their interactions with food, but they do not specifically state Sophie's preference for any type of muffin. Given the context, it seems likely that the question refers to a character from a literary work; however, the information necessary to determine Sophie's favorite kind of muffin is not present within the provided excerpts.
