Embodiments infer a total preparation time of a recipe. A recipe including preparation steps describing how to prepare a food item is obtained. A recipe server identifies preparation features in the preparation steps, where the preparation features represent portions of the preparations steps that are correlated with time to prepare the recipe. The recipe server obtains preparation times associated with the preparation features and combines these preparation times to estimate to total preparation time of the recipe. The estimated total preparation time is stored or transmitted to a client device in response to a request for the recipe. The estimated total preparation time is used to filter recipes sent in response to a request for recipes, where the request specifies a criterion based on total preparation time. The estimated total preparation time is used to select recipes for recommendation to a user based on that user's preferences.
