|Type of site||Recipe Search Engine|
FoodPair allows users to find and filter recipes based on ingredient, keyword, diet, course, number of ingredients and source site. The site's faceted search interface gives users with the ability to refine search criteria incrementally. A user typically begins a search by entering one or more ingredients and/or keywords. After being shown results, the user has the option to further narrow the results by applying additional filters. The filters allow the user to select recipes based on the number of ingredients, course (such as appetizers or main courses), or recipes from a particular website. 
FoodPair also lets users select recipes for their specific diet with filters for Low-Carb, Low-Fat, Vegetarian and Vegan Recipes. It is the only recipe search engine with locking filters, which help users save their diet, site and course preferences so they only have to enter them once.
User registration on FoodPair is free and optional. By registering, users are able to save their favorite recipes and use the unique locking filters. Other key features on FoodPair include a simple up/down voting system, recipe recommendations and content sharing via Facebook and Twitter. FoodPair also uses a "toolbar" feature so that users can still vote on or share a recipe even when they are viewing it on the host site.
While users are able to find recipes using traditional keyword searches on FoodPair, the site has received notoriety for its ability to save users money by using ingredients on hand.
In August 2010, PC Magazine included FoodPair in its Top 100 Sites of 2010. Other food related websites included in the list were AllRecipes and Epicurious. FoodPair was also named a Good Online Cooking Guide for the Beginner Cook by MakeUseOf.com. Trend Central recently featured FoodPair as a site that helps home cooks streamline their online recipe searching.
