Sidequest: Learn what one variable does to a cookie.

Design a controlled small-batch comparison that changes one ingredient or technique at a time and records observable results.

What I can provide: Base recipe, equipment, variable of interest.
Please deliver: A baking experiment sheet.

Ask only for missing information that materially changes the result. Otherwise, state reasonable assumptions and keep the scope manageable. Use reliable sources and link them. Verify time-sensitive details such as hours, prices, access rules, and availability when relevant. If you cannot verify a detail, label it clearly and give me a way to check it. If a required tool or source is unavailable, ask me for the relevant material or explain the limitation. Return a draft or plan for review; do not send messages, make bookings or purchases, or change my files or accounts unless I separately ask.
