When you find a recipe that you really enjoy, you can save it here in a custom collection! This works best if you are registered for the site, as then you can access your saved collections from any device. Otherwise you can expect to find them on the device you were using when you originally tapped the save button.
Saving recipes allows some additional functionality such as the ability to create shopping lists from one or multiple recipes, and scale entire collections at once! It’s all mobile friendly and printable too so you can check things off your shopping list from any device or just go old school with pen and paper.
