Recipe Recording by Duplicating and Editing Standard Recipe

The best way to ascertain the exact nutritional value of a user's food intake is to have the user record the recipe for that food himself/herself. However, writing a recipe from scratch is tedious and impractical. Therefore, we proposed a method that allows users to write their own recipe in a short time by duplicating and editing a standard recipe. We developed a smartphone application and conducted an experiment in which 19 participants were asked to write their own recipes for about 10 food items each. The results showed that the duplication method took 74% of the time compared to writing a recipe from scratch. The number of editing operations was also reduced to 45%. Future work is to construct a dataset of standard recipes that can be rewritten with little editing cost for any person's recipe.
