In this paper, we describe a mobile service, which is aimed at cooking chefs and that generates list of ingredients for recipes made of local products. We focus on a specific type of cooking recipes based on plants, which are used in cultural food practices worldwide to support wellbeing ("phytonutrition"). Researchers in food technology have been successfully developing food recommenders but there is a gap concerning the notion of phytonutrition changes the set of required functions and the theoretical framework to assess the software. We describe an endtoend support system for recipe design in compliance with European regulations concerning phytonutrients. Results of a longitudinal test, which was done in a hotel in the Alpine region, show that our software allows chefs to conceive a set of dishes, which increase the satisfaction of customers and have a positive effect on their wellbeing.
