I made this for fun with React and Go, its open-source if you want to hack it yourself. [1] I was inspired by the book "Make the Bread, Buy the Butter" by Jennifer Reese. I tried to continue the idea to see how much money+time it costs to continually substitute an ingredient for the recipe of that ingredient. Sorry for the ads - I use them to make back the $ spent on the domain :). I just toned them down. Please let…
Minor suggestions:
* Allow currency change (e.g. EUR instead of USD)
* Use + and - signs or green and red colors when hovering over the ingredients to show if money can be saved or not. Also put the amount of time in a different font size or color. (Site is very minimalist though which is great).
* Explain sources for price calculation (I'm skeptic about some, and curious who its based for).
