My girlfriend and I maintain a recipe book to keep track of all of the delicious food that we make. After searching the internet, largely in vain, for good recipe templates to format our new recipes, I decided to write my own R Shiny app generate nicely formatted PDF recipes. The implementation uses knitr within R Shiny to create PDFs from dynamically generated Latex and markdown. Implementation details can be found in the Github repository, and you can play around with the Shiny app here.
