I love using my Kindle in the Kitchen
I used to have one big file with my recipes in which I stored on the Kindle but I soon got fed up with amending the file every single time I wanted to add a new recipe. Too frustrating.
So now I type up each recipe (or copy a recipe from the web) into an individual Open Office document (you can use Word) - save as an HTML file and email this to my Kindle.
My Kindle ends up with lots of individual recipe files which I add into a recipe collection. So easy to search your Kindle to find what you want.
If you want more specific information on the processes I use, please visit my blog post:
Hope you find a method that works well for you.
