I have a small app which has Users, Recipes, Ingredients and preparation models

A user has many recipes, recipes belong to user and ingredients/preparation belongs to recipes.

Now a user can view all recipes but I would like the option to add the particular recipe to a favourites list. Would I need to set a new DB to hold this and then link by associations or could I add a column to the recipe model called fav for example?

Im looking for the best practice here or if someone has done this before and can offer any advice that would be appreciated
