Dosa - History & Preferences

preview

An iconic South Indian Dish

Was ‘dosa’, an accident? Oh! there is a story about this too, passed down since ages that a brahmin accidentaly created dosa. One more story involved a king’s ‘bawarchi’ or chef who didn’t want to waste food, so ended up with this idea of dosa.🫠

Nonetheless, an accurate time, place and person couldn’t be determined on how dosa became what it is today; “Favorite dish”. More like a traditional culinary dish passed down to generations in the form of backtories with several modifications. Anyway, I did my own digging to find if there are any references of dosa in the past and guess what, I found many!

Where is ‘Dosa’ data though?

I found data about pizza, burger, sandwich, spaghetti and meatballs but nothing about dosa. So, I tried to gather data on my own. I came up with a survey on google forms.

If you are interested in helping me gather data on dosa, please fill the surevy here: Dosa Survey.

Coming back to my quest of finding data on dosa, you might ask why dosa? Well, I love dosa. They are thin and crispy and I can gulp 10 dosas in one sitting. 🤣 Heard lot of stories about the dish and I loved my mother making dosa while I stood next to her with my plate in hands ready to be eaten. Can’t argue with mom’s cooking skills and home food. Home food is the best!🥰

So, what I did is grab the responses from the survey and work on this data.

Survey Data

Surveying was the fun part in this mini-project because I was more inclined towards spreading the survey to various groups of different ages. I hosted this survey on google forms and distributed in my Whatsapp groups, on LinkedIn, Instagram and on reddit. Survey contains no personal information; only choices, age in bins, geographical location-country. The questions are about a person’s preference of having various dosa with various chutneys.

Reached out to my peers and friends to spread the survey. I captured about 96 responses in 2 weeks. Well, its not bad and not the best either. At least close to 100 gives a good sample size for this project. I wanted to increase the complexity in this mini-project, so I crafted the survey in such a way that data is of ‘string’ type only. All the responses were ‘strings’ or text:

Then I trimmed my column names, since I didn’t have a big data problem I did it manually. Then loaded in my tableau.

Tableau Dashboard

Working with this dataset was fun and brought lot of hidden insights which I included on my dashboard.

Features of the viz:

a. Timeline and dates (excel can’t handle calendars before 1900, so I made new column; say ‘-500’ for BCE): to make a historical timeline.

b. Union and common table keys (created an Id ‘text’ so that I could join tables in tableau and plot).

c. Handling strings & Parameter calculations for percentages using “COUNT()” and “TOTAL(SUM())” to make pie charts since I have only 3 categories, pie charts are easy to understand.

Dashboard

Few of the questions I asked:

a. Is any chutney the most preferred choice for a dosa?

b. How many people know about dosa and how did they hear about dosa in the first place?

c. When do they prefer having dosa: breakfast, Lunch, dinner or snack?

d. Is there a trend between age group and dosa preference?

e. Where did people tasted dosa: Country?

Thus, I made the following dashboard.

One of the most interesting insight here is that no one preferred dosa as a snack!

Conclusion

The preferences of people are well visualized in this dashboard and saw that ‘dosa’ is spread across the world but I have to gather more data on this aspect. I need a bigger sample but for now, I got enough responses.

The dataset is available on my github and here is my link to the dashboard
