What Do I Cook?

A research-led exploration of the everyday cooking decision — why it exhausts working professionals, and what a technology-assisted solution might look like if it started from real behaviour rather than a feature list.

The everyday friction nobody talks about

The question "what do I cook?" sounds trivial until you have to answer it twice a day, every day, with limited time, a half-stocked kitchen, and a household that has opinions. For working professionals cooking their own meals, this small decision is quietly exhausting — and the alternatives (ordering out, eating at cafeterias) are either expensive or nutritionally frustrating.

Our starting problem statement, sharpened through a decision matrix across eight candidate framings, was this:

Being a working professional and short on time, eating healthy outside is getting expensive day-by-day and the food delivered is not personalised to my taste. I'm ok with cooking my own food provided it is quick. If there was a service that helped me do that, it'd be awesome.

That brief told us where the pain was. It didn't yet tell us why. So we went to find out.


Research method: a two-week diary study

We ran a diary study — not interviews or surveys. The reason was deliberate: cooking decisions are habitual, contextual, and often invisible to the person making them. A retrospective interview would have produced rationalised answers. A diary study caught the actual moment — what they cooked, why, what they skipped, and what frustrated them while it was still fresh.

7 participants
Working professionals aged 25–35, cooking at least five days a week for themselves or a small household.
2 weeks of entries
Daily food diaries capturing meals cooked, recipe sources consulted, ingredients on hand, and friction points.
Structured screener
Screened for cooking frequency, reliance on outside food, and openness to technology — to keep the sample tight.

Data cleaning, scanning, and the search for signal

Diary studies generate a lot of noise. Before we could look for patterns we had to standardise the data — cleaning inconsistent phrasing, tagging each entry by participant, and pulling every statement into a shared workspace where the team could scan across all participants at once rather than reading one diary at a time.

Left: affinity groupings beginning to emerge. Right: the full cross-participant scan before clustering.

Scanning across participants rather than within them was the move that mattered. Patterns that looked like personal quirks in one diary showed up as shared behaviour across three or four others. That cross-participant view is where the research started to become insight.


What the data kept saying

The decision-making insights database — built from every notable statement across all seven participants — was tagged by cognitive factor, type (individual, social, contextual), and the behavioural bias in play. Reading it top to bottom, two threads kept appearing.

Cognitive load at the point of decision
"I don't want to stand in front of the refrigerator and decide what ingredients are there and what to cook." — Nikita. The decision itself was the problem, not the cooking.
Variety fatigue and the monotony trap
"I got used to poha so much that I don't want to eat it anymore." Default recipes collapse under repetition, but trying new ones carries uncertainty cost.
Ingredients-first thinking, not recipe-first
"For trying out new recipes, I google and watch a few videos, decide recipe based on ingredients available." People don't browse recipes and then shop — they look at what's there and figure out what they can make.
Cooking isn't rewarding enough to feel worth it
Process of daily cooking seems boring. Social cooking — cooking for friends and family — feels good. Cooking for one on a Tuesday night doesn't.

The aha moment

All the threads pointed to one underlying truth. It wasn't that people lacked recipes. YouTube has millions. It was that finding the right recipe for right now — given what's in the kitchen, how much time they had, and what they'd eaten the past three days — was the actual unsolved problem. And once cooking felt like a chore with no payoff, the motivation to even engage with that decision collapsed.

My time is valuable and I need many quick and easy recipes. Cooking, for now, is not rewarding enough and is not encouraging me to cook.

That was the insight we chose to design against. Not "how do we teach people to cook" — but "how do we reduce the decision cost and give cooking a reason to feel worth it."


How we chose what to design

We used a weighted decision matrix to evaluate eight candidate How Might We statements against five criteria: relevance to insight (30%), potential market (20%), revenue potential (20%), skillset alignment (15%), and execution resources (15%). The matrix forced a rigorous conversation rather than a vote on instinct.

The decision matrix that anchored the problem selection — the same weighted criteria framework was later used to evaluate idea candidates.

The chosen HMW: How might we understand current cooking practices and provide tips and tricks that reduce time and offer varieties of quick and easy recipes?

From there, the same framework was applied to idea selection. The winning concept was direct: a recipe platform for Indians that surfaces recipes based on ingredients already in your kitchen.


Behavioural archetypes and decision patterns

Before moving to features, we mapped behavioural archetypes across the participant pool — not demographics, but patterns of decision-making. The archetypes distinguished the Habitual Cook (System 1 dominates: same five dishes, bought on autopilot) from the Aspirational Experimenter (high awareness of what they want to try, high friction at every step) from the Contextual Pragmatist (what I cook is determined by what's in front of me, not what I want).

These archetypes shaped what the product had to do well: for the Habitual Cook, it needed to introduce variety gently without overwhelming defaults. For the Aspirational Experimenter, it needed to lower the barrier to trying something new. For the Contextual Pragmatist, the ingredient-first search model was non-negotiable.

The decision analysis also surfaced a consistent cognitive load signal: people weren't avoiding complexity because they were lazy. They were avoiding it because there was no scaffolding — no guidance on ingredient freshness, no quantity scaling for one or two people, no indication of which steps could be done the night before.

Prioritised feature groups

The feature model was built from user stories rather than from what seemed technically interesting. Five feature groups, ranked in order of how directly they addressed the core insight:

Ingredient capture
Log what you have. The product can't serve the right recipe without knowing the starting point.
Ingredient-first recipe search
Surface recipes you can actually cook tonight — filtered by what's already in the kitchen.
Preference capture
Learn dietary norms, disliked ingredients, and household constraints so suggestions improve over time.
Recipe cooking tracker
Track what you've made so the system avoids repetition without being asked to.
Reward system
Address the motivation problem directly — make cooking feel worth it, not just efficient.
The user stories board mapping features to specific participant needs and moments in the cooking decision journey
User stories mapped to participant needs — each story traced back to at least two diary study entries to avoid features that were solutions in search of problems.

What I'd carry forward

This was an early project — done during a design diploma, in two weeks, with a team of five people all new to structured research methods. What it got right was the insistence on going to behaviour first. A diary study was harder to run than a survey and harder to analyse than interviews, but it produced data that a survey never would have — the unguarded moment when someone admits they're just going to make dal again because they can't face the decision.

What I'd do differently: the behavioural archetypes were built from a small, relatively homogeneous pool. The insight that "cooking is not rewarding enough" is real, but the reward mechanism that would actually shift behaviour probably varies significantly across those archetypes. The feature model I'd build today would be archetype-specific — a different onboarding, a different reward framing, a different default recipe surface — rather than a single platform trying to serve all three.

The principle that has stuck: when the problem is a decision, the design intervention needs to reduce the cost of making it — not add more information to wade through before arriving at it.
