Recipe selection system with bidirectional calendar interface

A computer system for recommending a recipe and monitoring preparation of the recipe according to a calendar, the computer system comprising one or more processors, one or more computer readable memories, one or more computer readable storage medium, and program instructions stored on at least one of the one or more storage medium for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:

• program instructions to receive, by a computer, calendar data that includes one or more of:
• a date;
• scheduled appointment times for the date and appointment durations;
• any special events on the date;
• and
• proximity of the date to a holiday;
• program instructions to identify, by the computer, one or more recipes that can be prepared in an available time slot in the calendar, wherein the one or more recipes includes a list of food from a food ingredient list;
• program instructions to monitor, by the computer, data associated with the preparation of a selected recipe, wherein the data includes a length of time to complete a preparation step of the selected recipe and the data is obtained via an optical identifier activated by a motion detector, and wherein the motion detector activates a light source for lighting a field of vision for the optical identifier;
• in response to detecting the length of time increasing by more than a threshold value, program instructions to adjust, by the computer, one or more of:
• one or more subsequent preparation steps of the selected recipe to compensate for the detected increase to the length of time;
• and
• the calendar to provide a longer available time for recipe preparation;
• and
• in response to adjusting the one or more subsequent preparation steps, program instructions to display, via a graphical user interface, the one or more subsequent preparation steps along with an alert depicting a potential dietary restriction and a plurality of images depicting the food ingredient list corresponding to the displayed one or more subsequent preparation steps, wherein the depicted potential dietary restriction alert corresponds to a user profile associated with the received calendar data.
