If he has a SparkPage set up, you can go to his SparkPage, hover over the "More" tab on the right side of his page, then click on favorites in the drop-down menu. You can then see the recipes that he has shared on there. Another option is to have your husband give you the url for that specific recipe you are looking for. Each recipe gets its own url, so if he gives/sends that to you, you will be able to go to that url and view the recipe.
My husband entered a recipe into the recipe calculator. I am trying to find it so I can add it to my tracker. But I can't locate it and there is apparently no way to search for it by his username or to look at his recipe box by username. Is there a way to do this that I am just missing? If not can you please add it?
