An electronic shopping system recommending recipes and creating shopping lists. A user selects items for purchase and proceeds to a point-of-sale terminal for checkout. The point-of-sale terminal transmits information of the purchased items to a network computer which uses the information to update a taste profile for the user. Based on the taste profile, the network computer recommends recipes that may be prepared using the items just purchased. The network computer also creates the user's meal plan for the week based on the user's taste profile, and provides the meal plan along with a shopping list.
