- I use Evernote. I have an Evernote notebook called "Recipes." When on the laptop, I use Evernote Clipper Chrome extension to my recipe notebook. It also clips nicely from my phone. I've tagged everything to organize recipes by types and ingredients. For the old-school paper recipes I want to include, I use the Scannable app, which integrates with Evernote and allows me to merge my collections nicely.
- For recipe discovery, Yummly is great. They have millions of recipes, 20 million users, they let you create shopping lists, and in some places they even let you order food for delivery/equipment to make a meal. Fun fact: they were recently acquired by Whirlpool and last valued at $100 million :)
