A new, fast recipe search engine was released by Silvio Rizzi (maker of Reeder and Mela), called Foodle.
Search by title or ingredient, and it provides a variety of sourced recipes to view or ingest into Mela, his RSS-based recipe library app. I’ve been really enjoying using Mela these last several years, and find it’s simplicity (basically RSS-focused pulls from virtually any source, including some social media) worth the investment of time. It also prints beautiful recipe pages (my preferred way of cooking is referencing physical copy).
