Related content gives you the ability to link from a recipe page, to another recipe or pantry item. These can be used for many purposes such as linking to a special video guide, or equipment used in a recipe. It may also be used instead of recipe components, if you want to link to a recipe, without adding its ingredients to a meal plan.
