Patent ID: 7299245

Claim:
A computer-implemented method comprising: receiving a first recipe; determining one or more second recipes that are similar to the first recipe based one or more factors, including a weighted ingredient coefficient taking into account sums of differences between relative contributions of individual ingredients between the first recipe and each second recipe and between each second recipe and the first recipe; and, outputting the one or more second recipes by one or more of: displaying the one or more second recipes to a user on a display device: and, printing the one or more second recipes by a user using an image-formation device, wherein the weighted ingredient coefficient as to the first recipe and a particular second recipe is defined as and determined as a first constant from which a second constant multiplied by the sums of differences between the relative contributions of the individual ingredients between the first recipe and the particular second recipe and between the particular second recipe and the first recipe is subtracted, wherein the greater the weighted ingredient coefficient as to the first recipe and the particular second recipe is, the more similar the particular second recipe is to the first recipe.
