In starting to make more cocktails at home, I ran into a few pain points while using recipe books: I often making drinks for more than one person and multiplying liquid volumes is tedious; and searching for recipes based on ingredients among multiple books is too much work.
There are a handful of cocktail recipe apps out there, but a common problem is that the recipe quality can be quite varied. Running my own service means that I can populate the database with only verified recipes. In addition, having added basic authentication means that I can store non-public recipes as well.
I chose Django for the backend because of its baked-in admin panel, which makes entering new recipes a breeze.
