Abstract: One variation of a method for preparing a frozen food product includes: following insertion of a vessel into a receiver: activating a cooling element thermally coupled to the receiver; transitioning a rotary motor from rest to a first target angular speed; and setting a first timer of a first duration; in response to expiration of the first timer and detection of contents of the vessel approximating a first target viscosity: reducing an angular speed of the rotary motor; and setting a second timer of a second duration; in response to expiration of the second timer and detection of the contents of the vessel approximating a second target viscosity: reducing the angular speed of the rotary motor; and setting a third timer of a third duration; in response to expiration of the third timer: reducing the angular speed of the rotary motor; and indicating completion of a frozen food product.
