FoodPair allows users to find and filter recipes based on ingredient, keyword, diet, course, number of ingredients and source site. 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.
