Do you keep recipes somewhere? A recipe book, an app, notes? How do you organize your recipes?

I use Paprika. It's amazing to keep organized and find your recipes. Also the recipe downloader is awesome. Just go to a site with a recipe in the in app browser and hit download and it automatically formats it for easy use. The app is $5 but the desktop apps are $29.99. I don't know why those are so expensive, but I ended up getting it because I'm at my desktop a lot and it's way easier to download the recipe there than moving to my phone. They all sync together too.

I promise this is not an ad, I just really like this app for recipe organization. What do you guys use?
