Personalized recipe app with dietary filters and ingredient substitutions
Home cooks and those with specific dietary needs often struggle to find adaptable recipes due to the inflexibility of traditional cookbooks and apps. This challenge, compounded for those seeking simpler and cheaper options, leads to frustration, wasted ingredients, and missed opportunities for enjoyable cooking experiences.
MixMaster solves this problem, allowing users to edit ingredients in existing recipes, change ingredient portions, and substitute ingredients using Gen AI. In this solo concept project, I worked end-to-end from ideation to design.

Research
User Interviews
I conducted a user interview and spoke with Na, a person who doesn't like to cook food and orders in food daily from food delivery services.
Portioning and waste issues
Na struggles with cooking portions, leading to waste and frustration due to inconsistent amounts of food.
Recipe Adaption Challenges
Na faces difficulties with adapting recipes and finding ingredient substitutes, compounded by unclear cooking instructions and videos.
User Journey Mapping
To better understand the needs and pain points of home cooks, I followed a Recipe App to put myself in the place of the user.
User Persona
Gathering ingredients was the biggest pain point of my cooking experience. This process was too expensive, time consuming, and it was difficult to get the correct portions that I needed.
